Dear sir,
I wants to design touch wall switch. Here i have to use TRIAC and MOC3021. My circuit not has direct neutral. because the neutral connected outer side of LOAD.
my citcuit just has two terminal , LINE and LOAD . But i need zero cross signals to triggering the load.So i cant able to give correct reference to get zero cross signal.
and also it has self oscillating transformer and bridge rectifier to create 5vdc for microcontroller...
any one help me to get correct zero cross signal without the neutral line on circuit.....
