The PIR Motion Sensor ... you can use multiple sensors and outputs to trigger different effects depending on your needs. The Arduino is capable of driving small loads like an LED without extra ...

To be frank, using a microcontroller is probably overkill for most motion detector ... regulator, and Arduino IDE compatibility. The code is an Arduino project for the Digispark Attiny85 to turn on a ...

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic ... correspond to where you plugged the PIR sensor and power relay into the Arduino.

If you have an Arduino ... sensor and determine which key to send using the Nicohood library. The serial communications is I2C and there’s a tiny optical sensor onboard along with an IR LED.

With just a Wemos D1 Mini, a standard PIR sensor, and some open source code, you can create a practical self-contained motion sensor ... this project is done. Using the Arduino Sketch [Eric ...
