Hello,
I am testing the external interrupts of the Arduino UNO (INT0 and INT1) and wanted to know what voltage to supply and how to supply the voltage to the pins. The hardware interrupt should trigger when the voltage is applied to the pin i.e. a SINGLE low to high transition. I wanted to know if I can directly connect/short the 3.3V output given by the arduino board to the INT0/INT1 pins? If this is not possible can someone give suggestions? What circuit should I use? Thanks!
