4. PIR Motion Sensor Motion sensing is useful for a range of applications, from intruder detection to home automation. PIR motion sensors use infrared light to detect movement.

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 ...

Makers and developers looking for a motion sensor Arduino Shield, are sure to be interested in this new ICU-Duino which has been created by Patrick Thomas Mitchell based in Ottawa, Canada. The ICU ...

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.

For his sensor, [Felix] is using a Moteino, a very tiny Arduino compatible board with solder pads for an RFM12B and RFM69 radio transceivers.

A few years ago Josef Holmner created an awesome Arduino powered wrist worn quadcopter controller that allows pilots to control their flying drones using just one arm, and gestures which trigger ...

The Leap Motion controller is a rather impressive little sensor bar that is capable of generating a massive 3D point cloud and recognizing hands and fingers to allow for gesture control based ...

Sometimes, the best Arduino projects are the most ridiculous. Case in point, this motion-detecting squirt gun. The idea is simple: when it detects motion, the spray gun activates.

The accelerometer uses sensors to detect the motion and speed of your hand, while the connected Arduino board will pick up on your motions and work out the commands.
