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.

A motion sensor activates the light when it detects something moving within its field of view. Photocells work with a resistor that changes its conductivity based on how many photons are hitting it.

Bang—motion sensor. Project Ideas Depending on the sensors and actuators you use and how you combine them, this fairly simple concept can do some surprisingly complex things.

Using motion detectors and an Ardunio you can add a little extra wow to your Halloween displays ... Here is the Arduino code for the Parallax sensor. int motion_1 = 2; int light_1 = 13; void ...

Motion sensors to consider: Eve Motion (Matter) — Smart Motion Sensor $39.96. Aeotec SmartThings Motion Sensor $38.99. Ring Alarm Motion Detector $29.99. Presence sensor.

This is a firmware application written in C++ using Arduino and Adafruit libraries. It sleeps in low power mode until, activated by the motion sensor, it takes a picture. Images are posted to io ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

An Arduino is a much better choice than a Raspberry Pi for tasks that require real-time input and responses. While a Pi can ...
