Common applications of flip-flops, latches and registers

Increase the number of inputs on a microcontroller

A commonly encountered problem when working with a microcontroller is not having enough GPIO pins to read in multiple sensors. A parallel input, serial output shift register can be used to read in the same number of inputs with fewer GPIO pins on the microcontroller.

Convert a momentary switch to a toggle switch

Some system functions require a toggle switch, for example the primary power switch for a system. This video quickly explains how to use a push button or momentary switch to perform this toggling.
