Polling vs interrupt an interrupt is an external or internal event that interrupts the microcontroller to inform it that a device needs its service interrupts vs polling a single microcontroller can serve several devices. Interrupts vs subroutines the difference is that when you call a subroutine, you call it when you decide, and you understand completely what will be changed by it could also increment a counter so that the non-interrupt code could time the number of interrupt ticks between switch changes.
