Arduino Electronics Lessons

Picture of Arduino IDE HardwareArduino is designed to make using a microcontroller easier. A microcontroller is a very small computer. The Arduino hardware (like an Arduino UNO for example), is the circuit board that has a microcontroller on it.

The following lessons are about some of the electronics associated with using Arduino boards. I hope you find them helpful!

Understaning Arduino High and LOW pin States

Understanding HIGH and LOW Arduino Pin States

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.…
