I'm putting an MPU6050 on an arduino Micro but the interrupt is different than the arduino uno. The external interrupt #0 pin on an arduino uno is pin 2 but its not pin 2 on an arduino micro. So I'm trying to figure out what pin it is on an arduino micro

The ATmega32U4 pin mapping says 3.

But pin 3 is the SCL. I'm using that pin to communicate an nrf24l01 Commented Nov 16, 2016 at 0:00

Well, you have the mapping now. Pick something. Commented Nov 16, 2016 at 1:33
