Arduino – Blink

Everyone’s First Arduino Project

The epinomous Blink example. This diagram can be used along side of your lessons to teach students the first and most basic of the Arduino sketches

Using the well loved Fritzing diagram tool our Breadboard diagrams are carefully laid out to communicate clearly the objectives of the lessons.


Fritzing File – These are included to help guide assembly of your project.

The Fritzing File includes everything you need.

  • Wiring Diagram
  • Schematic
  • PCB
  • Arduino Code

If you work with Fritzing you can wire the Arduino and Run the code right from Fritzing.

Arduino Code – Our custom commented code with the bare minimum to ease understanding.

If you want to use the Arduino IDE or or another coding tool you can download this code.

LED Artwork – Some artwork you can use around your Classroom or in any documents.

LED, Silicon, Anvil and Post

In order to support this page and my videos you can purchase an LED Diagram and the Above Artwork from TeachersPayTeachers.

LED Diagram / Poster


  • Arduino UNO
  • 1 – 5mm LEDs
  • Hookup Wire
  • Jumper Wires
  • Breadboard

Coding Directions

Preferably download the code from above ( you can also get away with using the built-in examples. ) The code is ready to run without modifications.

Connect your Arduino to the machine you are using and press the Upload Icon.

Wiring Directions

1st Let’s wire up the LED

Place the LED into the breadboard with the long leg ( The anode ) into colum 19 on your breadboard and th short leg into colum 20.

Add a Current Protection Resistor

Place one end of the resistor into colum 19 and the other end into colum 15

Connect the Arduino

Place one wire ( Red is a good color ) from Digital Pin 13 to colum 15 on the Breadboard

Place one wire ( Black can indicate a ground connection ) from colum 20 on the Breadboard to one of the GND pins on the Arduino

That’s all the wiring we need for this experiment.
