Introduction
In this tutorial you will learn how to add an on button that will provide power to your project for an amount of time and then turn off again. We will be using a Solid State Relay (SSR) to deal with AC (alternating current) voltages like what you would see coming out of your wall at your house.
PLEASE DON'T HURT YOURSELF! When dealing with high voltages, and high currents, please be extra careful and take any and all precautions.
