Re: ESP8266-01 gpio2 5v out to trigger relay

Posted: Sun Aug 14, 2016 2:06 amlast thing to solve then I have finally completed 
Everything is working, I have to set GPIO2 to HIGH after it is initiated but now the blue LED is faintly showing all the time and I don't think is healthy what could cause that to happen, i have checked continuity and doesn't appear to be anything touching that shouldn't be, 1 step away from closing this thread for ever lol Nearly there.

Posted: Sun Aug 14, 2016 3:03 amI had commented out serial begin and all serial prints and removed a delay which made it work but the LED stayed on, now I have uncommented serial print and re added the delay, the led is normal again, but now the switch wont switch.
EDIT it has just worked, will test some more
