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 ...

The code is an Arduino project for the Digispark Attiny85 to turn on a light source when the PIR sensor detects something. Note that after powering the PIR sensor module, it needs about 10 to 60 ...

4. Program the Arduino: Once the hardware is set up, you will need to program the Arduino Nano. The code for this project is available on the Instructables website.

This means it will cancel out different gestures if certain threads aren’t in motion. After a bit of smart programming using IR code and communication protocols, you can set the movements to ...
