Day 3: Lesson – Fun with LEDs

You are here: Home / 30 Days to Arduino Programming Course / 30 Days to Arduino Lessons / Day 3: Lesson – Fun with LEDs

Today we have fun with Arduino + LEDs, using multiple LEDs at once, AnalogWrite, we create a Tardis effect and a Knight Rider/Cylon “Larson Scanner”, plus we show off colour with an RGB LED.

The foundation for all the examples today is this circuit.

You will need

  • 5 LEDs
  • An RGB LED if you have one
  • 5 220 ohm resistors
  • A breadboard, Uno, USB cable, and wires
