For that ones of you that have already read my articles Web Power Switch for MAINS and the : WIFI MPSMv2 MAINS Switch DevBoard, you surely remember that the above modules were ON/OFF switching only.

Now it's about time to talk also about DIMMING!

MPDMv3 is a MAINS Power Dimmer module with Zero Cross Detection circuit:

Well friend, I read your article must say JOB WELL DONE (y)

I did about same with 8051 few years back but only with resistive load. But now I guess will try it with ESP8266 and inductive load. Few things I want to clarify:

1. Can we use Inductive circuit (with snubber) for resistive load, vice-versa not possible ofc.
2. Can we test BT1xx circuit with simple 12V sinusoid waveform from function generator.
3. For simple ON-OFF function, is it better to use thyristor or simple mechanical relay.

Thanks for the time
