Re: Voltage output range for TZXDuino? aka trying to get it wokring

Hello....I don't think you are detecting both zero crossing points in the full cycle. To detect both you will have to feed the input of the H11A1 AC via a full wave rectifier, so both positive and negative cycles conduct through it.
