Using motion detectors and an Arduino you can trigger lights, fans, or even an pneumatically controlled cleaver-wielding clown to help add your house to the “if you dare” list.

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 ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The … ...

As indicated, our system requires a “Logic High (H)” level input to wake up. The best sensor you can use to detect an intrusion is the Passive Infrared (PIR) Sensor. The PIR Sensor detects the motion ...

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.

What he came up with is a light-sensitive motion sensor that uses very little power. He knew that an Arduino would be overkill, and decided to try his hand at using the Arduino to develop code for ...

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

Components Needed: Raspberry Pi 4. Arduino Uno. 4-channel relay module. PIR motion sensor. Steps: Use Arduino to handle sensor input and relay control. Pi runs a Python Flask server with a simple UI ...

Anyone searching for an Arduino project to keep them busy this weekend may be interested in a new motion activated wildlife camera constructed using the Adafruit Feather M0 development board.
