Use a Common Anode RGB LED
This is a quick tutorial on how to fade between colors with an Arduino and Common Anode RGB LED.
Jumper Wire
Hands-Free Mouse
Make a mouse for your computer that uses only an Arduino, an accelerometer, and your head movement to move and click.
Labyrinth Video Game
This guide will teach you how to build and program your own accelerometer controlled maze game. It does assume a basic knowledge of soldering, breadboards, and programming in Arduino. by the end of this guide you should be able to make your own maze by editing the code and then solve it by tilting your […]
Security Box
This is a very simple box design using a small box (a shoe box or smaller works) with a simple lock mechanism to represent the opening of the box. When you get the code right, a green LED lights up and the servo moves, unlocking the box (or at least making it easier to open). […]
LED Sound Meter
In this guide you will learn to created an array of LEDs that visually represent the volume picked up by an electret microphone. You will learn how to wire 3 different circuits which are the LED array (which is really many individual circuits), the microphone, and a button which can be used to change the display mode […]
Railroad Grade Crossing Signal Controller
This project guide explains how to build an operating railroad grade crossing signal controller (GCSC) for controlling a simulated railroad crossing signal that has working flashing lamps and striking bell. Just like the real thing! This board was also designed with hacking in mind. Due to the on-board 5 VDC power supply and extensive breakout […]
