Arduino Breadboard

The Arduino website serves as a central reference for Arduino projects and programming.

Built-In Examples

All built-in examples have their own page that provides instructions and information on how they work.


Every function, variable type, and structural statement has its own page with examples and instructions on how to use it.

Examples & Challenges:

Start by setting up the breadboard and downloading .zip file. Extract, then upload example programs to Arduino.

Start each stage by reading and uploading the example, then modify it or write your own program to replicate the challenge.

The “answer key” is provided, but try to figure out each challenge before you read the program provided.

After completing all five challenges, try the Nano-Shield or Neon RGB to better understand Arduino programming.

0. Getting Started

Uploading Programs

Select port, board, processor, and upload Blink example.

Modifying Programs

Modify Blink to use pin 3 (LED on breadbaord) and increase blink speed.

1. If Statements

Example (A)

Use if statement to turn on LED1 when button is pressed.

Challenge (B)

Turn on LED2 when LED1 is off.

2. Serial Monitor & Plotter

Example (A)

Use analogRead to display potentiometer value in Serial Monitor and Serial Plotter.

Challenge (B)

Display button state (pressed or not pressed) in Serial Monitor.

3. Analog Inputs & Outputs

Example (A)

Use potentiometer to control LED1 brightness directly, and LED2 brightness adjusted to a single range.

Challenge (B)

Blink between LED1 and LED2, and use potentiometer to control blink speed.

4. While Loops

Example (A)

Use while loops to toggle LED on/off when button is pressed.

Challenge (B)

Start with Blink program, but pause program when the button is pressed.

5. For Loops

Example (A)

Use a for loop to fade LED up from off to full brightness.

Challenge (B)

Fade LED up from off to on, then down to off again, and at an increased speed.

Uno vs. Nano

All the examples on the Arduino website are for Arduino Uno, but you will be using the Arduino Nano (they are very similar).

When using diagrams for the Uno, make sure to use the same pins on the Nano and you should see the same effect.
