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 – Eduardo Cunha Nov 16 '16 at 0:00
  • Well, you have the mapping now. Pick something. – Ignacio Vazquez-Abrams Nov 16 '16 at 1:33
