LedFx

LedFx is an interesting open-source application designed to control LED strips connected to wireless hub/chips such as the ESP8266, ESP32, or Raspberry Pi 4. The idea is to convert audio input into visual output, transforming music into a beautiful and colorful LED light show. The app itself is more of a web interface from where you can connect, access, and control your LED strips.

The application is simple to operate, provided you've managed to understand how the physical wiring should be done for the lights to be visible for the program itself. One can manage already added devices, contribute to new ones, and adjust the movement of existing devices. Either way, the program is useless for more common devices found on the markets, especially since the above-mentioned chips are essential in this equation.

The program sends signals through your machine's wireless module towards one of the three compatible chips, communicating directly with these through their integrated wireless communication module. If you've soldered your LED strip the right way, the chip itself should further be able to send the received signals to the lights and begin directing their movement for a final and colorful light show. This process is repeated as much as needed in order to create the desired effect.
