Hello,
anybody can help me find a good circuit for zero crossing detector for 200V/50Hz signal? I prefer a circuit without transformer. I am going to use its output to be an input signal for PIC16f877 microcontroller. it is a light dimmer project.
I tried to google around but all I could find is an analog light dimmers!
Thanks,
