This voltage can be read by an Arduino digital input and then the Arduino can act upon it. The PIR Motion Sensor on the left is made by Parallax and sold by Radio Shack. The one on the right comes ...

The controller consists of a battery-powered Arduino ... accelerometer. Held in the hand, the controller streams accelerometer data to an external PC, capturing the characteristics of the motion.

Makers, developers and hobbyists looking to at the ability to monitor motion ... Arduino project may be interested in a new breakout board offering an all-in-one 9 Degree of Freedom (9-DoF) sensor ...

Accelerometers are increasingly ubiquitous ... in MEMS manufacturing techniques that have allowed the sensors to become smaller and more sensitive. Most are based on detecting the motion of a test ...
