Introduction

The General Purpose Input Output Header, known as the GPIO, is one of the things that stands out compared to "normal" computers. The pins of the GPIO give you the ability to have your Raspberry Pi talk communicate with just about anything. Here are just a few things that can be leveraged with the GPIO Header:

• Turning on and off LEDs, Motors and Speakers

• Receiving digital inputs from sensors and monitors

• Communicating with other computers over a serial port

• Chaining multiple devices or sensors using different interface protocols

This is just a short list of what is possible, and once you get comfortable using the Raspberry Pi Zero GPIO, you'll be able to have it control or communicate with just about anything!
