IRForum

One user reported that the IR send pin on Leonardo changes from pin 3 for UNO and similar ATMega328 class Arduinos to pin 13 for the Leonardo.

I found that the output pin for IRsend for the Leonardo is pin 13 instead of pin 3 (https://github.com/shirriff/Arduino-IRremote/issues/12)

We understand that pins vary on a selection of different models and the alternative pin definitions can be found by looking at the souce code for the library, which can be found on the github site above.
