If you are just getting started with Arduino, you might be wondering what the heck all this HIGH and LOW stuff everyone is talking about really means.

At first I just figured everyone using micro-controllers was just on some type of emotional roller-coaster, until I began to realize that HIGH and LOW are actually abstractions.

But let us not talk in abstractions - let us talk in concrete numbers and get down to the bottom of what HIGH and LOW actually mean.

This Tutorial Will Include:

What the heck is a PIN state?
What are the values for Arduino Pin States?
Practical Application: What do we see in practice?
