Dr WHO, I’m trying to make D1 act just like D2, but I’m having trouble. I added
OCR2A = Brightness; to
a5nightLight and pin 20 is still the only one with nightlight-related activity.
Then I found
TCCR2A = (_BV(WGM20) | _BV(COM2B1))and added
TCCR2B = (_BV(WGM20) | _BV(COM2B1)), although I don’t fully understand what that does. Still nothing on pin 21.
Can you suggest something else to try?
