Project Overview: This project presents a simple yet effective automatic lighting system using an Arduino microcontroller, an ultrasonic sensor (HC-SR04), an LDR (Light Dependent Resistor), and an LED ...

This project uses an LDR (Light Dependent Resistor) with an Arduino UNO to automatically turn on an LED when it's dark and sound an alarm when it's bright.

Here is a simple Arduino Camping Light project. In this design, only one push button switch is used to control the light output (from a bunch of white LEDs) between off, dim, medium, and full ...

One of the easiest tricks to keeping a house warm (or cool), is to open and close the blinds in time with the sun. Of course, that's only helpful if you're home all the time to do that. Instructables ...

[Hazim] wrote in to tell us about his project that teaches inconsiderate drivers a lesson! Well, theoretically. The LuxBlaster is a spot light which points towards the most intense light source. The ...
