Not only will the motion-sensing alarm protect your gear from animals and zombies alike, the project can help you get started with Arduino.

It’s compatible with the Arduino IDE and also contains a USB port for easy programming. The Trinket is hooked up to a GY-521 accelerometer, which allows it to detect motion.

If you've always wanted to try to build an Arduino project, this may be a great way to start. Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by ...

What he came up with is a light-sensitive motion sensor that uses very little power. He knew that an Arduino would be overkill, and decided to try his hand at using the Arduino to develop code for ...

TK has combined a PIR with an Arduino to create a smart safety light for the house or workshop. Follow along as this gets built out into a more extensive project.
