- Sun Aug 14, 2016 3:03 am #52894 I 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
