Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

Arduino-Motion-Sensing-LEDs The goal of this build project is to turn LEDs on and off with a motion sensor.

Using motion detectors and an Ardunio you can add a little extra wow to your Halloween displays this year. This article covers the circuits and the code to make that happen.

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 ...

English: Code to control an LED connected to pin 8 of the Arduino Uno based on input from a PIR motion sensor connected to pin 9. The LED turns on when motion is detected (HIGH signal) and turns off ...

Make sure the adjustment knobs for sensitivity and on-time for the motion sensor are facing up so you can modify how sensitive your device is and how long it stays on to signal your Arduino.

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.

Build a Speed Sensor using Arduino with IR speed sensors to accurately measure the speed of moving objects. This tutorial covers circuit design, sensor calibration, speed calculations, and optimized ...

This report introduces an innovative, low-cost approach to using Arduino as a measurement tool for scientific investigations in education. When using Arduino for science investigations, teachers and ...
