Attached is a screenshot of a wiring scheme that I have set up for testing. assume that the top power rail is 5v and the bottom is 3.3v
If I power on the esp32 with the wiring just the way it shows here, it wont actually start up.
if i removed the LLC and do 3.3v to VCC and remove the jumper for the JD-VCC and put 5v to that pin, it works (going directly from esp32 pin to IN1) only if i have 1 relay on. I am using the relays to switch 120v.
I have been working on circuits for about 6 months. so not an expert here. can someone tell me why this doesnt work?
