=== Part 1: Set up your 5V power supply===
Set up the voltage regulator on your breadboard. This chip (a "5 volt regulator") takes your input voltage (12V from your adapter), and turns it into 5 Volts. Here Below is the diagram of how a 5 volt regulator is set up:. It takes an INPUT voltage ("+12V" on the left), and turns it into an OUTPUT voltage ("+5V" on the right). It also needs to be connected to GROUND.
