Wifi controller for LED strip and lamps Designed for convenient control of LED lighting. Preset software allows the ice Wi-Fi controller to simulate dozens of different dynamic lighting options.
The Led wifi controller is equipped with touch or push-button control and, via a DMX signal, controls the LED power circuit, setting color and brightness parameters, as well as the speed of color change.
Maybe Wifi connection controller for LEDs 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 in time with the music playing. You can buy such an audio controller at most stores that sell LED products.
This controller for an LED strip works on the principle of supplying signals from a music center and redirecting them to an LED device. Some models of these devices do not require direct connection 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 flow of LEDs, pulsation, sharp and smooth transitions from color to color in time with sound signals, etc. The controller is usually controlled using a remote control. Adjusting the brightness of the LED strip, selecting the glow mode of several sections of the strip installed in different zones premises, 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 an LED strip in order to create original light and sound lighting for the interior. Prices for audio controllers for LED strip depend on the number of control channels (2, 3, 4), 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 strip is easy to connect: it is soldered directly to the LED strip; you just need to take into account the load for which the device is designed and do not exceed the recommended length of the strip when connecting.
A device for controlling color to the beat of music can be used not only for LED strips, but also for lamps. Price for audio controllers for LED lamp usually no higher than for devices for LED strips.

Color music - drums with LED lighting
Light up your drums with the sound of the beats. This guide will help you upgrade your reels to get reliable dynamic LED lighting. 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 significantly lower than other projects. It is very compact and can be powered by small batteries!
We made an assembly for a snare drum, a mid drum, and a bass drum. 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 doesn’t look bad at all. Our project will cost a third of the price of other 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 at 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:
NeoPixel: http://learn.adafruit.com/adafruit-neopixel-uberguide
Adafruit Gemma: http://learn.adafruit.com/introducing-gemma
To complete the project you will need:
Drum set Gemma microcontroller Mini microphone Mini switch Lithium polymer battery NeoPixel LED strip Necessary tools for soldering and assembly 3D printer (if available) The diagram below shows general principle connection of elements:
The digital input of the NeoPixel LED strip is connected to the “D0” pin on the Gemma controller. The negative pole of the LED strip power supply is connected to the “GND” pin, the positive pole is connected to the “Vout” pin (not to 3vo). The microphone is connected to pins A1/D2 on the Gemma controller - this is the analog input of the controller. Power to the microphone is supplied from the “3vo” pin on the controller. The Gemma controller acts as a voltage regulator, converting 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 completely 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 make the program fit your design. For starters, we can easily change the number of outputs and the number of LEDs. In our setup, each drum uses 60 NeoPixels LEDs.
You can read the manual for working with the Arduino IDE program at the link:

You can learn how to change colors depending on the frequency of the sound from this description:

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, this was no problem for us. If it is difficult for you to access it, then you can come up with something of your own suitable for placing these components. Just in case, a file with a 3D model of the case:
LED_Drum_Case_for_Gemma.zip
The essence of the assembly is that the manufactured case, together with the installed microphone, Gemma controller, switch and battery, are installed on a special bracket in the area of the ventilation holes outside the drum. Only NeoPixel LED strips can be placed inside the drum.
The step-by-step assembly of the installation is clearly shown in the photographs below:
This completes the assembly process. Lithium batteries can be easily removed for recharging. Our battery lasts for about an hour, but you can use more powerful ones.
