Learn how to submit your Arduino-based project. It may even get featured on the Arduino social channels!

I really want to make a Raspberry Pi laptop but just can't find the right size trackpad so in this project we will be salvaging an old one.

Plug in a device to your computer, push a button, and things happen! Several different modes do useless things with your mouse/keyboard.

Accukey lives!

Use FreeRTOS (simple, easy, robust, & optimised for the Arduino IDE) to reduce the power required for battery or low power applications.

Back when I first started working with micro controllers, the most annoying thing was when a tutorial I'd spent hours following didn't work.

Connecting Arduino with accelerometer ADXL345 to Box2D with Qt framework.

Showing a simple way to use a flashtube with high voltage generated using Arduino.

Avoid SD card corruption on a non-responsive RPi using an Arduino to log into the serial console and restart your RPi from the root account.

Hack an old controller and use it as a combination of a keyboard and a mouse.

Basic and useful 4x4 T9 keypad, to text message.

Most of USBasps are not able to program at 3.3V. Some say they can switch between 5V and 3.3V, but not signal pins, e.g. MOSI.

A novel input device implemented with a binary tree.

Show simple way to generate high voltages with Arduino and an example (flash-tube) how to use it
