Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

This Arduino lights dimmer project is based on Doug Hitchcock’s comment: “I need to have a lamp dimmer that can “cascade” from one lamp to the next (up to 4 lamps). Basically, when you close a switch, ...

Arduino RGB Button Control This is an Arduino project that controls RGB LEDs using push buttons. Each button controls one LED color (Red, Green, or Blue). When a button is pressed, the corresponding ...

Want to control the colors in your home? Sure, you could just buy a Philips Hue bulb, but where’s the hacking fun in that? [Dario] agrees: he has written a tutorial on building an Arduino-con… ...

The entire system is built on the backbone of an Arduino Uno with a few other parts totaling at about $150. That seems expensive, but DeBoisblanc's build covers a lot of ground.

Check out the final results -- which feature 3,300 mini lights, 3 spotlights, an LED Rope, 4 LEDs, and one magical reindeer -- in the video after the break.
