In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

We know that LED is a two terminal semiconductor device. It is used in most of the electronic circuits as a sign or visual representation to the normal human to know that circuit is working properly.

Nearly everyone’s first electronic project is something that blinks a LED. There are a million ways to go about this ‘Hello World’ project of electronic design; 555 timers, microcontrollers, or maybe ...

I needed a simple LED indicator showing that a particular voltage level had been reached—specifically, that a capacitor had charged to a particular potential. I was convinced that there must be a way ...
