There will be a programmable 12V dimmer for LEDs with an ATmega8 soon. Just created to use some empty space on a PCB.

Small dimmer for 12V devices like cheap LED strips.

I have created this projekt because thier was some empty space an a 10x10cm pcb. The most importen feature is the support of I2C und UART wich other dimmers with NE55 doesn't have and also the price. The max Power is ca. 50W (conductor = 40mil).
