Interrupt with Touch Sensor

Interrupt routines can be very useful!
They are used to interrupt the main program to respond to external events.

Interrupt should not do something long and complicated. Most of them will only remember if some specific event has happened and then in the main code that information will be used.

An interrupt alerts the processor to a high-priority condition.

Schematic is almost the same as in the previous video, except for one additional button.
