LESSON 14: Expand your Pins with Shift Registers

Now that you know how to connect a variety of components to your Arduino, you’ll be inspired to build larger and more complex projects. But what happens if you don’t have enough pins for your creation? That’s where shift registers are helpful. They only require 3 pins on your Arduino and you get 8 outputs – not a bad deal! We’ll be working with the 74HC595, or 595 for short, one of the most popular ones for electronics projects.
