Arduino Motion Sensor – Circuit and Working The circuit diagram of the automation device using a motion sensor is shown in Fig. 2. It consists of an Arduino Nano board (MOD1), a PIR sensor (S1), a ...

This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute (RPM). You don’t need much… ...

If A was selected, the system would immediately count down from ten to allow the user to clear the area of motion. Once the system was armed, a red LED would light up to indicate its armed status. If ...

When everything’s plugged in, this is how your Arduino, motion sensor, and power relay should look. Jeremy S. Cook. Plug the male-to-female jumper wires into the motion sensor pins.

All you need is an Arduino, a motion sensor, a few wires and headers, and the code provided at the site below. Hit the link to see step-by-step instructions on how to put it together.

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 ...
