This is the first of several practice projects to get you comfortable working with the Arduino and building breadboard projects.
In your first Arduino project, we will not be using any code for the project. We’ll just be using the Arduino to supply power to a light-emitting diode, or LED. When the Arduino is plugged into a computer or battery, it can function as a power supply, and that’s how we are going to use it here.
When this project is correctly wired up, the LED on the breadboard will light up and stay lit as long as your Arduino is plugged into your computer via the USB cable.
This is a very simple project, but it will let you practice inserting components correctly into a breadboard and safely/properly connecting a breadboard to an Arduino to draw power from the power pins on the Arduino.
