How to Add Multiple Inputs to an Arduino using a Shift Register
In this fourth and final video about shift registers, Karen shows how to use them to add inputs to an Arduino. Using one or more parallel-in serial-out shift registers, 8, 16, or more inputs can be added by using only 3 Arduino I/O pins.
