google for "arduino mega pin mapping" or "arduino uno pin mapping"

both turn up good results.

How do I find out which Arduino pins are related to for example DDRA on my Arduino Mega 2560?


Google arduino pinout and see the images.

Thanks for all the the replies very helpful.

Haven't had time to work out if that gives me access to PE2 on the 32U4 yet.
