Detecting motion using PIR modules is straightforward due to their digital output and the ease of integration with Arduino. In this simple article from DigiKey, it demonstrates how to turn on an LED when a user passes in front of the sensor.
In this project, we will see how to turn any decorative object into an IOT smart device. Specifically, a plant pot was chosen and it was transformed into a device that sends movement notifications. The heart of the project is an ESP-01 WiFi module for wireless communication and a PIR sensor to detect movement. An…
This tutorial shows how to detect motion with the ESP32 using a PIR motion sensor. In this example, when motion is detected (an interrupt is triggered), the ESP32 starts a timer and turns an LED on for a predefined number of seconds. When the timer finishes counting down, the LED is automatically turned off. More…
If you are searching for a cool project for Christmas, for sure it’s not like an amazing house light system, but instructables user Magesh Jayakumar has created something you’ll find inspiring: a wearable light system! Hello all, do you want to Make something fun and cool for the holiday season , here’s an Instructable for…
The Shy Machine is a motion activated, sound reactive, environmentally adaptive and arduino-powered kinetic light sculpture. When it detects motion via a PIR sensor, the shell-like robot takes a reading of the ambient sound level using an internal microphone. If things are sufficiently quiet, it opens up using a stepper motor and lead screw, revealing…
Fans of Valve’s innovative and unique video game series Portal should check out a recent Instructables page published by a user called Stephen Gioiosa. As part of a maker course at the University of Florida, the Portal enthusiast 3D printed a replica of Aperture Science sentry turret, one of the game’s iconic turrets. The results he achieved are pretty impressive for…
