Arduino LED Flasher Circuit

In this project, we will go over how to build an arduino LED flasher circuit. We will use a standard arduino board, doesn't matter which, and connect it so that it flashes an LED a certain amounts of times on and off repeatedly to create an LED flasher circuit. An arduino is a self-contained microcontroller. Therefore, it can be programmed via the language Processing to turn the LED on for a certain period ...
