An I²C Bus powered Arduino IO Expander Board controlled via Bluetooth and Android

Today we'll expand Arduino's digital resources thanks to an bus equipped shield and we'll allow the management of the board via a bluetooth connection

Servo Driver Circuit Schematic

How do you build a simple circuit to control a servo?

Schematic Diagrams: Joule Thief

Today I am showing you how to make a very simple joule thief. A joule thief has many applications, the best gadget that I made with was a "Water Powered.

In this project I will show you how you can make this cool looking Arduino Radar using the Arduino Board and the Processing Development Environment.

This is a demo video of the Arduino Radar Project. The Radar uses an ultrasonic sensor for detecting the objects, a small hobbyist servo motor for.
