In this lesson we show you how to measure distance using the HC-SR04 ultrasonic sensor. We review the concept of dimensional analysis to help you understand how to get the correct units.

You can get the kit I am using for this series at the following link:

I strongly suggest picking up an arduino nano, since it can plug directly into the breadboard, making a portable system more practical. You can pick one up here:

As projects get more complicated in these lessons, you guys really need to get a set of breadboard jumper wires which allow you to make neater connections on the board in your projects. You can pick a pack of these wires up here:

In addition as projects get more complicated, you are going to need a bigger breadboard. This is a reasonable one here:
