Blink the Onboard LED

Requires

Welcome to this beginner-friendly project where you’ll learn how to make the built-in LED on your Arduino board blink using Code Kit. This simple project is perfect for those new to programming with Arduino and Code Kit. You’ll send code from Code Kit to your Arduino board, making the LED turn on and off repeatedly—an excellent introduction to coding concepts like loops and delays.

In this project, you will:

  • Use Code Kit’s block-based interface to create a program.
  • Upload the code to your Arduino board.
  • Watch the built-in LED blink in action.

Parts List

Here’s what you’ll need:

  • Arduino board
  • USB cable

Assembly Instructions

  1. Plug one end of the USB cable into your Arduino board.
  2. Connect the other end to a USB port on your computer.
  3. Check that the Arduino is powered on—you’ll see lights on the board indicating it’s working.

That’s it! Since we’re using the built-in LED, no extra wiring is needed.
