Hi, I am having some trouble using the Pro Mini using a interrupt that is external to get 2 LEDs to flash for 5 seconds and print to the serial monitor. I have used some examples and I wrought my own programming and still no luck. I am basically using a sensor that is High to Low or Low to High. Once this sensor engages, I need it to do an interrupt and flash the LEDs on pin13 or the built in LED and also an LED on pin10 or any other I can change the circuit to accommodate a different output pin.
I was wondering if anyone knew of some simple programming to achieve this? I also am wondering if I have to use a pin change or state change between two pins to achieve this instead of the INT1? Thanks
