Hi. I don't know how to close a thread. I'm starting this one.

To control AC devices I found this schematic:



I hope this image is showing....

OK... I built it in a breadboard and it's not working. I used a 15W lamp. The uC is sending 1,0,1,0 to Gate.

If I connect a LED it flashes with the signal sent to Gate but the lamp never turns on. What can be the problem? I'll post the code, but there's no problem with it as it is sending the signal to GATE.

I'm using a MOC3011 and a TRIAC MAC12M or a TRIAC MAC223.

How can I test the MOC 3011?
How can I test the triacs?
