This circuit consist of 8 dimmer outputs.
There is a zero crossing detect so the sketch can power on the TRIACs at the needed time.
The zero cross side has not been tested, but should work.
Opto + triac side of the circuit is already working with a PIC Microcontroller, so should also work with an Atmega !
1 input for L+N, and 8 outputs which consist of 8 L+N. So you don't have to break circuits, just plug lights.
Small loads only should be used (about less than 100W), since I didn't let enough space for heatsinks. I however didn't calculated the triac limits.
1A Temporized Fuse should be placed on each output (fuse holder is on board), which correspond to 220W limit....
Warning : Resistors values have not been calculated, I should update them soon. 2nd Warning : I did not put any anti-parasit circuit (L+C) on the output side. I plan to use this circuit with 220V LED lights only, and those lights doesn't work correctly with L+C circuits.
