Color Music - Drums with LED Lighting
Light up your drums from the sound of beats. This guide will help you upgrade your drums to get reliable dynamic LED backlight. This project uses a microphone as a sensor and a Gemma controller to make the NeoPixels LEDs work in time with the drums. The cost of this project is much lower than other projects. It is very compact and can run on small batteries!
We made an assembly for the snare, medium, and bass drums. Each drum is independent of each other, but if the sound from the neighboring drum is loud enough, then the neighboring drums can also react to it, which looks pretty good. Our project will cost a third of the price of other offered drum kits on the market! There are other tutorials that use the "Piezo" element and a few additional components (capacitors, resistors, timers, etc.), but our tutorial makes it much easier to achieve success with a fairly low cost of components, microcontrollers, sensors and LEDs.
Before completing the project, we strongly recommend that you read the instructions for working with the following components:

To complete the project you will need:
Drum Set Gemma Microcontroller Mini Microphone Mini Switch Lithium Polymer Battery NeoPixel LED Strip Required Soldering and Assembly Tool 3D Printer (if available) The diagram below shows general principle element connections:
Digital input led strip The NeoPixel is connected to the "D0" pin on the Gemma controller. The negative power pole of the LED strip is connected to the "GND" pin, the positive one is connected to the "Vout" pin (but not to 3vo). The microphone is connected to the A1/D2 pins on the Gemma controller - this is the analog input of the controller. Power is supplied to the microphone from the “3vo” pin on the controller. The Gemma controller acts as a voltage regulator, converting the battery voltage to a constant 3.3V to power the microphone, while the LEDs are powered by 5V. Accordingly, the "GND" contact is common to both voltages.
Before fully soldering your circuit, we recommend assembling a test circuit using the quick assembly principle:
After assembling your circuit, you need to do programming. The Gemma controller is programmed via USB using the Arduino IDE program. You can change and customize the code to fit your schema. For starters, we can easily change the number of outputs and the number of LEDs. In our setup, each drum uses 60 NeoPixels LEDs.

The process of assembling the entire drum kit
In our project, we used a 3D printer to make an acrylic case in which we placed the microphone and the Gemma controller itself. Since we had it in stock, it was not a problem for us. If you find it difficult to access it, then you can come up with something suitable for placing these components. Just in case, a file with a 3D model of the body:
LED_Drum_Case_for_Gemma.zip
The essence of the assembly lies in the fact that the manufactured case, together with the installed microphone, Gemma controller, switch and battery, are installed on a special bracket near the ventilation holes outside the drum. Only NeoPixel LED strips are placed inside the drum.
The step-by-step assembly of the installation is well shown in the photos below:
This completes the build process. Lithium batteries can be easily removed for recharging. Our battery lasts about an hour, but you can use more powerful ones.

Wifi controller for LED strip and lamps Designed for easy control of LED lighting. preinstalled software allows the LED Wi-Fi controller to simulate dozens of different light-dynamic backlight options.
Led wifi controller is equipped with touch or button control and, by means of a DMX signal, controls the power supply circuit of the LEDs, setting the color and brightness parameters, as well as the speed of changing the color gamut.
Wifi controller for LEDs can be connected to any standard DMX signal receivers.
Audio controller– additional device for LED lamps and strips, connects to audio equipment and allows the LEDs to light up in different modes to the beat of the sounding music. You can buy such an audio controller in most stores selling LED products.
This LED strip controller works on the principle of sending signals from the music center and redirecting them to the LED device. Some models of these devices do not need to be connected directly to audio equipment. The audio controller may be equipped with a microphone (or microphone jack) that picks up sound waves and emits light signals according to the rhythmic pattern of the music. There are many different modes for such light music - slow overflow of LEDs, pulsation, sharp and smooth transitions from color to color to the beat of sound signals, etc. The controller is usually controlled using remote control. Adjusting the brightness of the LED strip, selecting the glow mode of several segments of the strip installed in different areas of the room, can be carried out using one remote control.
Devices for light and sound control of LED strips and lamps are convenient for use in bars, restaurants and clubs, where festive events and discos are often held. In addition, nothing prevents the use of such a device for use in your own apartment - it can be an interesting gift for music lovers, you can also buy audio controllers for LED strip in order to create original light and sound lighting for the interior. Prices for audio controllers for LED strips depend on the number of control channels (2, 3, 4), the maximum load and the number of available options.
The music controller can be designed for single color or multi-color LED strip (RGB), while the number of modes even in the simplest device is at least a dozen. The controller for the RGB tape is easy to connect: it is soldered directly to the LED strip, you only need to take into account the load for which the device is designed, and do not exceed the recommended tape length when connecting.
A device for controlling color to the beat of music can be used not only for LED strips, but also for lamps. The price of audio controllers for an LED lamp is usually no higher than for devices for LED strips.
