Shift registers are often used to increase the number of I/O pins on a microcontroller.
For example, If your project needs to control 16 individual LEDs, you will, of course, require 16 pins of an Arduino, which is not possible. This is where the shift register comes in handy.
With two shift registers connected in series, you can control 16 LEDs with only three I/O pins. That is quite a difference, and the more shift registers you chain together, the more pins you’ll add. In theory, by daisy-chaining shift registers, an infinite number of I/O pins can be added.
