What was your first Arduino program? Probably an LED blinker — that seems to be the “hello world” of microcontrolllers. You probably moved on to things a little more complicated p… ...

Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

The Etch a Sketch toy has gone more or less unchanged for over 60 years, but if you’re handy with a soldering iron you can build an upgraded version that swaps aluminum powder for glowing LEDs.

Description: In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever ...

The pixels draw a maximum of 60mA per pixel at 5VDC (20mA each for red, green and blue). These are individually addressable RGB LEDs. That means, we can make each LED turn any one of 16 million ...

Our RGB matricies are dazzling, with their hundreds or even thousands of individual RGB LEDs. Compared to NeoPixels, they’ve got great density, power usage and the price-per-LED can’t be beat.

An optional RGB LED attempts to copy the shade of whatever object you’re aiming at, providing a handy reference to verify it’s working correctly. “ Watch this video on YouTube.

Patrick's da Vinci is nothing less than a classic Etch-a-Sketch driven by stepper motors and controlled by an Arduino. Oh – and the frame and gears are all laser-cut, just to bump the coolness ...
