Arduino Tutorial 10: Understanding How To Read Analog Voltage using analogRead Command

So far in these lessons, we have just been using the Arduino output pins. If we actually want to read values from a sensor or other such components, we need to learn how to read values from the analog pins. These are pins A0 through A5. This lesson will teach you all about the analogRead command that allows you to interact with these pins. Enjoy!

In this new series of lessons, I will be using this Arduino kit.
