Need a Zero-Cross Detector

Postby Zaygraveyard » Tue Nov 29, 2011 7:12 am

I am making a light dimming program that triggers an SSR connected to a lamp.
The problem is that I need to repeat the triggering signal every time the AC crosses zero and for that I need a Zero-Cross Detector.
Is it possible that you make a Zero-Cross Detector that can be connected as a sensor (Analog Input) or using the digital input.

Maybe use a opto-isolator package to detect zero-crossing points.
