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.

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.

The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

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 ...

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 ...

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.

Hot glue the motion sensor to the hole you drilled for it. Feed the wires through their respective holes and attach them to the Arduino and the power relay. Reattach the enclosure’s top cover.

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.
