Learn Programming and Electronics with Arduino

Apr 7, 2017

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:

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