Mike Cook has published another simple and fun project that you can build around an Arduino board - his "Sneak Thief" game. It uses an infra-red sensor to detect changes in light around an object that can be "stolen". If you can remove the object slowly enough the alarm will not sound, however if you do it too quickly, the light level changes abruptly and the alarm sounds. For example:
This is a great example of a project for beginners or to entertain and educate younger people. It can be easily built around a standard Arduino-compatible board, such as our Freetronics Eleven - the Arduino Uno-compatible with onboard prototyping area.
