I'm not sure if this has been answered somewhere already, but just out of curiosity, what type of signal is coming out of the PIC to control the channels? Is it PWM? If so, why is it that we don't see the lights flicker when they are on? Or is the frequency of the pulses so fast that we can't perceive the 'flicker'? I guess this is how you can get variable brightness per channel just by modulating the frequency of the PWM, right?
Sorry, there's not really a functional question in here, but I was just curious how this worked
Neat stuff!
