Intro: Bringing a LED to light up

Let’s start with with a very easy project. You need there no programming knowledge to create this project.
It’s only a LED which is lit. Here you learn to deal with the LED, the breadboard, a resitstor and a switch.

In our lessons we use mainly the USB-Connection as power supply for the Arduino.

What you need:

  • Arduino UNO
  • Breadboard
  • LED
  • Resistor -> 220Ω
  • Switch

The goal of this construction is, to flash the LED with the help of the Arduino as power supply and the switch to control the lighting state of the LED.
