  • IN: I bought a tape with contacts G, R, B, 12 on it. How to connect?
    A: This is the wrong tape, you can throw it away

    IN: The firmware loads, but the error “Pragma message...” appears in red letters.
    A: This is not an error, but information about the library version

    IN: What should I do to connect a ribbon of my own length?
    A: Count the number of LEDs, before loading the firmware, change the very first setting in the sketch, NUM_LEDS (the default is 120, replace it with your own). Yes, just replace it and that’s it!!!

    IN: How many LEDs does the system support?
    A: Version 1.1: maximum 450 pieces, version 2.0: 350 pieces

    IN: How to increase this number?
    A: There are two options: optimize the code, take another library for the tape (but you will have to rewrite some of it). Or take Arduino MEGA, it has more memory.

    IN: Which capacitor should I use to power the tape?
    A: Electrolytic. The voltage is 6.3 Volts minimum (more is possible, but the conductor itself will be larger). Capacitance - at least 1000 uF, and the more the better.

    IN: How to check the tape without Arduino? Does the tape burn without Arduino?
    A: The address strip is controlled using a special protocol and works ONLY when connected to a driver (microcontroller)

  • YOU CAN ASSEMBLE THE CIRCUIT WITHOUT A POTENTIOMETER! To do this, use the POTENT parameter (in the sketch in the settings block in the settings signal) assign 0. The internal reference voltage reference source of 1.1 Volt will be used. But it will not work at any volume! For the system to work correctly, you will need to select the volume of the incoming audio signal so that everything is beautiful, using the previous two setup steps.

  • Version 2.0 and higher can be used WITHOUT an IR REMOTE, modes are switched with a button, everything else is configured manually before loading the firmware.

  • How to set up another remote control?
    Other remote controls have different button codes, use the sketch to determine the button code IR_test(versions 2.0-2.4) or IRtest_2.0(for versions 2.5+), available in the project archive. The sketch sends the codes of the pressed buttons to the port monitor. Next in the main sketch in the section for developers There is a definition block for the remote control buttons, just change the codes to your own. You can calibrate the remote control, but honestly it’s too lazy.

  • How to make two volume columns by channel?
    To do this, it is not at all necessary to rewrite the firmware; it is enough to cut a long piece of tape into two short ones and restore the broken electrical connections with three wires (GND, 5V, DO-DI). The tape will continue to work as one piece, but now you have two pieces. Of course, the audio plug must be connected with three wires, and the mono mode is disabled in the settings (MONO 0), and the number of LEDs must be equal to the total number on the two segments.
    P.S. Look at the first diagram in the diagrams!

  • How to reset settings that are stored in memory?
    If you've played around with the settings and something goes wrong, you can reset the settings to factory settings. Starting from version 2.4 there is a setting RESET_SETTINGS, set it to 1, flash it, set it to 0 and flash it again. The settings from the sketch will be written to memory. If you are on 2.3, then feel free to update to 2.4, the only difference is the versions new setting, which will not affect the operation of the system in any way. In version 2.9 there was a setting SETTINGS_LOG, which outputs the values ​​of settings stored in memory to the port. So, for debugging and understanding.

To assemble LED color music with your own hands, you must have basic knowledge electronics, be able to read schematics and work with a soldering iron. In the article we will look at how LED color music works, the basic working diagrams on the basis of which you can assemble ready-made devices yourself, and at the end we will step-by-step assemble the finished device using an example.

Color music installations are based on the method of frequency conversion of music and its transmission, through separate channels, to control light sources. As a result, it turns out that depending on the basic musical parameters, the operation of the color system will correspond to it. This trailer is the basis for the scheme for assembling color music on LEDs with your own hands.

Typically, at least three different colors are used to create color effects. It can be blue, green and red. Mixed in different combinations, with different durations, they can create an amazing atmosphere of fun.

LC and RC filters are capable of separating the signal into low, medium and high purity; they are the ones that are installed and configured in a color music system using LEDs.

Filter settings are set to the following parameters:

  • up to 300 Hz for a low-pass filter, usually its color is red;
  • 250-2500 Hz for medium, color green;
  • everything above 2000 Hz converts into a high-pass filter, as a rule, the operation of the blue LED depends on it.

The division into frequencies is carried out with slight overlap, this is necessary to obtain different color shades during operation of the device.

The choice of color in this color music scheme is not important, and if you wish, you can use LEDs of different colors at your discretion, change places and experiment; no one can prohibit it. Various frequency fluctuations combined with the use of a non-standard color scheme can significantly affect the quality of the result.

The circuit parameters such as the number of channels and their frequency are also available for adjustment, from which we can conclude that color music can use a large number of LEDs of different colors, and it is possible to individually adjust each of them in frequency and channel width.

What is needed to make color music

Resistors for color music installations, produced in-house, can only be used constant, with a power of 0.25-0.125. Suitable resistors can be seen in the figure below. The stripes on the body indicate the resistance value.

The circuit also uses R3 resistors, and trimmers R - 10, 14, 7 and R 18, regardless of type. The main requirement is the ability to install on the board used during assembly. The first version of LED color music was assembled using a resistor variable type with the designation SPZ-4VM and imported - tuning.

As for capacitors, you need to use parts with an operating voltage of 16 volts, no less. Can be any type. If you have difficulty finding capacitor C7, you can connect two smaller capacitors in parallel to obtain the required parameters.

The capacitors C1, C6 used in the LED color music circuit must be capable of operating at 10 volts, respectively C9–16V, C8–25V. If, instead of old Soviet capacitors, you plan to use new, imported ones, then it is worth remembering that they have a difference in designation; you need to determine in advance the polarity of the capacitors that will be installed, otherwise you can confuse and damage the circuit.

To make color music, you will also need a diode bridge with a voltage of 50V and an operating current of about 200 milliamps. In cases where it is not possible to install a ready-made diode bridge, you can make it from several rectifier diodes; for convenience, they can be removed from the board and mounted separately using a smaller board.

The parameters of the diodes are selected similarly to the diodes used in the factory version of the bridge.

LEDs should be red, blue and green. For one channel you will need six of them.

Another necessary element, Voltage regulator. A five-volt stabilizer is used, imported, with article number 7805. You can also use 7809 (nine-volt), but then you need to exclude resistor R22 from the circuit, and instead put a jumper connecting the negative bus and the middle terminal.

Connect color music with music center, you can use a three-pin jack connector.

And the last thing you need to have for assembly is a transformer with suitable voltage parameters.

General diagram for assembling color music, which uses the parts described in the photo below.

Several working schemes

Below we will propose several working schemes for LED color music.

Option #1

Any type of LED can be used for this circuit. The main thing is that they are super bright and different in glow. The circuit works on the following principle: the signal from the source is transmitted to the input, where the channel signals are summed and then sent to a variable resistance. (R6, R7, R8) Using this resistance, the signal level for each channel is adjusted, and then sent to the filters. The difference between filters is in the capacity of the capacitors used to assemble them. Their purpose, as in other devices, is to transform and purify the sound range within certain boundaries. These are the top, middle and low frequencies. For adjustment, adjustment resistors are installed in the color music circuit. Having gone through all this, the signal goes to a microcircuit that allows you to install various LEDs.

Option No. 2

The second version of LED color music is distinguished by its simplicity and is suitable for beginners. The circuit involves an amplifier and three channels for frequency processing. A transformer is installed, which can be dispensed with if the input signal is sufficient to open the LEDs. As in similar circuits, adjustment resistors are used, designated as R4 - 6. Any transistors can be used, the main thing is that they transmit more than 50% of the current. Essentially, nothing more is required. The circuit can be improved, if desired, to obtain a more powerful color and music installation.

Step-by-step assembly of the simplest color music model

To assemble a simple LED color music you will need the following materials:

  • LEDs measuring five millimeters;
  • wire from old headphones;
  • original or analogue of transistor KT817;
  • 12 volt power supply;
  • several wires;
  • a piece of plexiglass;
  • glue gun

The first thing you need to start with is to make the body of the future color music from plexiglass. To do this, it is cut to size and glued together with a glue gun. It is better to make the box rectangular. The sizes can be adjusted to suit you.

To calculate the number of LEDs, divide the adapter voltage (12V) by the operating LEDs (3V). It turns out we need to install 4 LEDs in the box.

We strip the cable from the headphones, there are three wires in it, we will use one for the left or right channel, and one for the common one.

We don't need one wire and it can be insulated.

The diagram of a simple LED color music looks like this:

Before assembly, we lay the cable inside the box.

LEDs have polarity, so when connecting, it must be taken into account.

During the assembly process, you should try not to heat the transistor, as this can lead to its breakdown, and pay attention to the markings on the legs. The emitter is designated as (E), base and collector, respectively (B) and (K). After assembly and inspection, you can install the top cover.

Ready-made version of LED color music

In conclusion, I would like to say that assembling color music using LEDs is not as difficult as it might seem at first. Of course, if you need a device with a beautiful design, then you will have to spend a lot of time and effort. But to make simple color music for informational or entertainment purposes, it is enough to assemble one of the diagrams presented in the article.

simple scheme of color music using 220V lamps

Everyone knows and almost everyone assembles this device that flickers and blinks to the music - color music. On the Internet, many search for color music schemes using various queries and they are different everywhere. I present to your attention the diagram below appearance which you see in the pictures. And so, circuit of working color music for 220 Volts on teristors

A simple color scheme


It will require the bare minimum of parts.

We buy colored incandescent lamps 220V
Considering that the output stage of the color music is made of thyristors, it has a lot of power. If thyristors are placed on heat sinks, then each channel can be loaded with 1000 watts. But for a home, 60-100 watt lamps are quite enough.

Drawing printed circuit board for light and music

I did not use laser-iron technology for such a simple board design. I simply printed the image as a mirror image and placed it on the foil.


To prevent the paper from moving, we secure it with tape or something else and mark the places of future holes

We paint the tracks themselves with nitro paint


Any transformer from a Chinese power supply, whether from a radiotelephone or something else, will be suitable as a transformer.

And look at the completely soldered board


We attach the cartridges to the aluminum corner



In addition to the photo sent

It's hard to find a person who doesn't like listening to music. To satisfy this desire, high-quality music centers, speakers and other devices are purchased. To get even more pleasure, many people think about creating special color effects that can decorate any sound and create a romantic atmosphere on a date or a fun mood when organizing a holiday party. Color music, like music centers, can be purchased, or you can make it yourself. The best option is to make color music using LEDs according to one of the proposed schemes.

Advantages of LED products

The modern electronics market presents a wide variety of LED strips that have a wide variety of color effects. With their help, you can create high-quality spot lighting; it is possible to create color music with flashing or blurry effects.

Unlike conventional light bulbs, LEDs are characterized by big amount positive characteristics. Among the main advantages of LED strips are:

  • wide and varied range of colors;
  • rendering rich colors;
  • different design options - rulers, modules, discrete elements, RGB strips;
  • high response speed;
  • minimum amount of energy consumed.

The ribbons can be used at home, in clubs and cafes, and can be used to effectively illuminate shop windows. This article will describe in more detail the option of LED color music for ordinary home use.

Simple circuit with one lamp

To begin with, it is worth studying simple diagram color music. This is a device that consists of one LED, transistor and resistor. Power for such color music can be supplied from a constant current source with a voltage of 6-12 volts. The device operates on the principle of an amplification stage with a common emitter. The impact in the form of a signal varying in frequency and amplitude arrives at the main base. As soon as the oscillation frequency exceeds a certain threshold value, the transistor opens and the LED immediately flashes.

This scheme has one drawback - the blinking rate of the LED depends entirely on the level of production sound signal. In other words, the light effect will be activated only at a certain level of volume produced by the music center. When the sound intensity decreases, the glow will be constant with occasional winks.

Scheme with one-color ribbon

This color music on a transistor is assembled using an LED strip in the load. To organize such color music, you will need to increase the power supply to 12 V, find and install a transistor with a maximum collector current that exceeds the load current, and you will also need to recalculate the total value of the resistor. Such color music is quite simple, made on one single-color LED strip and is ideal for beginner radio amateurs. You can assemble it without any problems at home.

Simple three-channel circuit

To get color music that is free of all the disadvantages listed above, you should use a special three-channel sound converter. This circuit is powered constant voltage 9 V and is able to effectively illuminate one or two LEDs in each channel. Among the main structural elements that characterize such a color-musical scheme are:

  • three independent amplifier stages, which are assembled using transistors of the KT315 (KT3102) category;
  • LEDs of different colors are included in the transistor load;
  • For the pre-amplification element, a network small step-down transformer can be used.

The incoming signal is fed to the secondary winding of the transformer, which in turn performs two main functions - it decouples two devices at the galvanic level, and also amplifies the sound from the main linear output. After this, the signal is sent to three parallel and connected filters, assembled on the basis of RC circuits. They operate on an individual frequency band, which directly depends on the value of the capacitor and resistor.

Color music with RGB tape

This attachment circuit operates on 12 volts and is ideal for installation on a car. This color music optimally combines the main functions of the previously discussed schemes and is able to work both in the lamp mode and in the color music mode. The second mode is achieved through special non-contact control of the RGB strip via a microphone. As for the lamp mode, it is based on the simultaneous launch of the green, red and blue LED at full power. The mode can be selected using a special switch located on a special board.

To understand how this attachment works, it is worth studying its sequence of actions. The main source of the signal here is a microphone, which converts sound vibrations emanating from the phonogram. The received signal is insignificant and therefore requires amplification. This can be achieved by using a transistor or a special operational amplifier. After this, the automatic AGC level controller starts. It effectively keeps sound fluctuations within reasonable limits and prepares it for subsequent processing. Built-in filters divide the signal into three parts, each of which operates in one specific frequency range. Finally, you just need to amplify the previously prepared current signal. For this purpose, special transistors are used that operate in key mode.

Purchase of a ready-made CMU

If you don’t want to make a color music system for use at home, you can purchase a CMU, that is, a color music installation. This is a ready-made functional solution that includes a controller. It will process the sound, converting it into a light and music visual representation. In the process of reproducing the light, its intensity and color scheme will change, thereby creating the effect of a real disco. The CMU device also includes a panel with built-in diodes.

These devices may be based on a spectral decomposition into frequencies, where each of them will have a specific color scheme or preset adjustments with a variety of effects and their alternation. They can be configured using the included remote control.

Important! Modern CMUs are very simple to install and configure. This is an ideal solution for organizing a home party or disco.

Conclusion

There are quite a lot of schemes for independently performing color music settings. You can choose a fairly simple option, where the color of the RGB tape will simply change, to quite complex ones, which in the process of work will create a large number of different effects, overflows and attenuations. Depending on your skills, you can choose and execute the appropriate option. It is enough to work a little and create something truly unique; it will be lighting equipment that delights with the shimmer of a wide variety of color shades. Also, do not forget that there is always the opportunity to buy a ready-made color music solution and fill your home with color shades and joy.

Homemade color music

Homemade color music in the interior of your own car will be of interest to all lovers of beautiful disco music. Making it with your own hands is absolutely easy.
Color music at home can be quickly and easily assembled if you know some of the nuances of the circuit and its correct installation.

Color music schemes in cars

A large number of homemade color music schemes are published on amateur radio forums. Some of them are intended only for experienced, others for beginners.
In principle, all circuits are built according to the same principle, which is recommended to be understood so that the assembly no longer represents something impracticable and very complex.

Simple scheme

Even a schoolchild can assemble color music using this scheme, because it consists of only one transistor. Its name is KT815G.
This color music can be assembled using diodes borrowed from a simple flashlight.
Everything is done as follows:

  • We divide the LEDs that we removed from the flashlight in half;
  • We find a suitable box in which we will assemble our circuit. In this case, instead of a box, a rectangular plastic box from used shoe polish is ideal;
  • We take out the switch. It will change the light-music mode to simple lighting.

Note. The LEDs will flash with bass and the higher the volume, the brighter they glow. As for the channels, two are enough, not connected to the speaker.

  • The power source in our case will be three AA batteries;
  • All that remains is to put homemade color music into the trunk and enjoy the effect.

Complex circuits

They will allow you to create more professional schemes from the user's point of view.

First version of the scheme

It is assembled on five diodes. All of them are five millimeter and 3 V, have clear lenses. The transistor used is KT815 or KT972. Its task is to strengthen and act as a key.
Everything is done like this:

  • Power is supplied from 2 1.5-volt batteries;
  • There are respectively two inputs for music: X1 and X2;
  • In place of LED3 we install a red diode, the remaining remaining pairs will be blue and green;

Note. As a result, we get a very successful color and music scheme. The LEDs glow very effectively to the beat of the music, the circuit consumes little current, and low frequencies are reproduced simply superb. You just need to be careful: the LEDs may not be able to withstand loud music and burn out.

Second version of the scheme

We find the KT817 transistor, wires, headphone plug and SD tape.
Started:

  • We solder the transistor according to the following scheme;
  • Then the CD tape is added and everything is moved to the luggage compartment of the car.

Light music from garlands

A completely successful solution that will require the use of light bulbs from New Year's garlands:

  • Garlands (see) need to be collected together in several pieces and secured with electrical tape;
  • Make an adapter to connect to the head unit and connect the wire.

Note. The circuit in this case will involve eight twisted pair conductors, which transmit the signal from the contacts of the control unit to the color music control unit.

Color music from LEDs

An original scheme for making beautiful color music. In this case, you need a housing made of plexiglass.
Let's get started:

  • We select two plates measuring 5x15 cm and two square plates 5x5 cm;
  • A couple of holes are made in one of the parts (for power supply and headphones);
  • We mat and sand all the plates;
  • We find LEDs that we also matte for a better effect;
  • We assemble the body using a heat gun, which is ideal for working with plexiglass;
  • Let's collect now electrical diagram for color music according to this scheme:
  • We connect the wire from the headphones with the corresponding connector to the car radio and enjoy the effect.

The plexiglass case can be installed in the car interior, anywhere. Everything will depend on individual preferences, wire length, etc.
During the work process, the following must be taken into account:

  • The output voltage of the adapter and the rated voltage of each diode must be interconnected. In other words, the total number of diodes involved in the circuit must equal the ratio of the adapter's output voltage.

Note. As an example, if the adapter is 12V, and the voltage for each diode is 3V, then the total number of LEDs should be 4.

  • It is advisable to use a 3-core wire, one of the wires of which should be left unused.

Circuit with signal from speaker

Another popular scheme for creating color music.
We do the following:

  • We take the signal from the speakers (see).

Note. In this case, it is very important not to short-circuit the output of the SPD*. For this purpose, we solder only one wire.

UZP* - Sound card amplifier

  • Arranges the switch so that it turns on the LEDs based on music;
  • We select the resistance according to the diagram below, where the rating for turning on one diode is indicated;

Note. If the color music will be assembled from 4 LEDs, then the R value should be equal to 820 Ohms.

Popular multi-color scheme

Another common scheme involves the possibility of increasing nutrition. This will be especially true if a chain of many LEDs is used.
The scheme is like this:

  • There should be two frequency filters. They allow HF and LF to pass through at the input;
  • The signal then goes to the amplifier stages, and then to the LEDs;
  • It is recommended to connect inputs 1 and 2 to the source speaker.

Advice. If you want to make color music brighter, then you just need to reduce the resistor values ​​to a couple of hundred, and change the transistors to KT817.

This scheme has one advantage that no other has: the ability to use LEDs of any color.
So, when playing low-frequency bass, the red LED will blink, while playing midrange and high-frequency – green. As for setting the brightness, it is regulated by the sound volume rotary: the higher the sound, the brighter the glow.

Car ceiling in LEDs

If you wish, you can not only arrange something similar to a disco in the car, but also build a backlight that would either turn on separately or be associated with music playback. This operation also involves the use of LEDs.
“Starry sky” on the ceiling of the car will look wonderful. This type of lighting, it turns out, has been practiced for a long time, and not only in cars, but also in our own apartments.
This scheme can be used in different ways:

  • Place the LEDs evenly, in any shape or like a certain figure;
  • Use light bulbs of different power, simulating the glow of stars (bright/not bright);
  • Use different ceiling backgrounds. For example, you can drag it black.

Creation instructions:

  • We drag the ceiling of the car;
  • We assemble or purchase a current stabilizer.

Note. It is very important at this stage to do everything correctly. Otherwise, you will have to dismantle the assembled ceiling if the diodes burn out. To avoid this situation, you need to check the circuit after assembly (find out how many volts and how much current the circuit has). An old power supply from a computer is suitable as a test unit.

  • We use a capacitor large capacity to smoothly dim the LEDs. For example, KT470 is suitable;
  • Place the diagram in a matchbox;
  • We check the operation by connecting three LEDs and one resistor in series;
  • On the ceiling, we insert LEDs into the holes, which are fixed on the back side with glue;
  • We also attach the switch and stabilizer.

Note. The LEDs can be grouped in groups of 3 and connected to a resistor, and then the groups can be routed to the stabilizer in parallel.

That's it. We hope that the reader will be able to choose something for himself from the given diagrams. Just remember to take care not to turn on beautiful color music while the car is moving. This greatly distracts you from the road and can cause an accident.
In the process of working with your own hands, a video review on the topic, photos - materials, diagrams, etc. will be useful. Instructions similar to those given above can be found in other articles on our site. The price of independently creating and installing color music is considered the lowest in the world of auto tuning, because consumables can also be made by yourself.
