You can fade out and fade in the light of an LED automatically by using Arduino and a simple code that is described below. Even though the Arduino board cannot output variable voltage on its digital ...

[Alex] planned to use an Arduino to control this display, but it doesn’t have enough outputs on its own to control all of those lights. He ended up using multiple 74138 decoder/multiplexer IC ...

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 ...

The Arduino-powered display is built from a strip of 35 RGB LEDs. Now, that’s four pins per LED but one of is ground, leaving just 105 pins that need to be addressable. A couple of things make ...

You can use any knit sweater, but light-colored ones work best, as the LED light will bounce around more. A loose fit is key, too—it’ll prevent the string of lights from showing and it’ll be ...

How to Light Your Jack-o'-Lantern the Arduino Way. ... If you want to try this out using a resistor and an LED, here is a simple Arduino UNO Sketch that will dim and brighten the LED in this circuit.

Can't afford a stage lighting designer for your band's next concert? A group of MIT engineers show how to hack together a Wi-Fi-enabled LED light fixture that responds to music in real-time.
