Pot as interrupt generator

Design Tip

Pot as interrupt generator
In battery-powered, microcontroller driven circuits, as well as with microcontrollers operating in cars, it is desirable to switch the micro into power-down mode once a task has been completed. An interrupt request is then required to wake up the micro. This circuit allows an interrupt to be generated in a simple way using a common potentiometer.
