Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites ... The code is an Arduino project for the Digispark Attiny85 to turn on a light source ...

PIR Pin “out” connects to Arduino Digital 2 Here is the Arduino code for the Parallax sensor int motion_1 = 2; int light_1 = 13; void setup(){ pinMode (motion_1,INPUT); pinMode (light ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close ... receiver IR1 is only ...

When everything’s plugged in, this is how your Arduino, motion sensor, and power relay should ... You can even plug a light or another device into the other normally OFF port to make it motion ...

Most ambient lights and sensors are designed to generate light to even out the picture on the front of the panel and reduce any light bleed from the back of an LCD display. This Arduino-powered ...

Because his blinkenlight shield can be used as a light sensor, all that’s needed is a mirror and a pretty long line of sight. There’s a few problems with the setup though: with the Arduino ...

This isn’t about connecting a temperature sensor in your Arduino. This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno ...
