Basic 12V RGB LED strips controlled via PC, through a web interface.
Schematic:
Single sided PCB:
Built PCB
Editable Proteus file can be found in pcb/rgbleds.pdsprj.
Firmware for the AVR ATMega8L can be found in the firmware folder. It requires an avr-gcc installation.
The RGB strips are expected to have 4 pins (+12V, R, G, B) and are connected to the PCB using "DuPont" clone connectors.
The software to control the LEDs can be found inside web/index.html, and it can be opened directly in any modern Chrome version, without requiring any server.
This project was originally created around 2014. The WebSerial interface was an example developed in 2020. The finishing touches were completed in 2021.
