Let's use Arduino to make a light that turns on automatically only when someone approaches and turns off after a while.This ...

Connect everything exactly as shown in the diagram above. PIR pins: VCC → 5V, GND → GND, OUT → D2. Servo wires: red → 5V, brown → GND, yellow → D9. Then plug the Arduino into your laptop via USB. Open ...

Welcome to Day 8 of the 100-Day Arduino Masterclass! Today, we explore motion detection. We will interface a Passive Infrared (PIR) sensor with the Arduino to build an intrusion alarm that activates ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

The (r)evolution Arduino motion sensors have been specifically built for projects that require the addition of self tracking applications based on information from your body. Watch the video after the ...

In the microcontroller era today, Arduino is more than just a tool to accomplish hobby tasks. There is actually a close relationship between microcontroller technology and home security, since you can ...

When you think of Arduino projects, your mind likely goes straight to RFID door locks, weather sensors, or automated plant watering systems. While these are undeniably pretty cool projects, you might ...
