This project is for those who want to control room light according to their mood. RGB mixing lamp is great in generating various colour schemes. It can work as stand alone device without PC connection.
It can be controlled remotely via standard RS485 bus system. RGB lamps are developed as stackable modules. If you want to build one – be prepared to develop four separate PCB’s for power supply, Atmega8 controller board, LED board and serial connectivity board. It has two firmware versions developed on ASM and C languages. Turn on deep blue colour and watch “The Abyss”.
