AC Dimmer Circuit: 46

Green wire is zero_cross signal, goes to Arduino digital pin 2 in. Yellow wire is light dimming signal, comes from Arduino digital pin 11. The LED on board should dim or fade along with the AC light source. Fading will not work until AC power is connected, it depends on the zero-cross info from the H11AA1 chip. Code example with slow on/off fade: example with potentiometer control:   Diagram Click for full- ...
