As the regular LEDs are too small to be noticeable, you can replace them with bigger LEDs or even a light bulb (paired with a relay for the Arduino Uno).

This project solves that problem by hooking up LED lights beneath a bed, then triggering them with a motion controller and an Arduino.

In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

If you searching for an LED matrix for your next project or to add to an existing application you may be interested to know that the Maker LED Display is now ...

– RAM: 3bytes WS2812B & Arduino Earlier we controlled LED matrixes, strips and other complex LED projects bundled with countless interconnected wires with the help of multiplexers and shift registers.

(Google Translate) The wiring for this project is about as easy as you’d expect: the buttons connect to the digital inputs on the Arduino, and the LEDs on the digital outputs.

[Jose] has been featured here before for his innovative Arduino-driven RGB lighting projects, and this is another great project which builds on that theme!

If you've messed with Arduino, the inexpensive micro controller, you'll know that you can run a small motor or turn an LED on and off, but anything else - powering a pump, turning on a light bulb ...
