To replicate Krejci’s design, you need an Arduino UNO Rev3 board, an AMG8833 infrared sensor module, and an 8×8 RGB LED matrix ... to download the source code to create your very own Arduino ...

This is a great building block for a future project using the Velostat or the RGB LED. It will also prepare the user on how to successfully hook the Velostat up to an Arduino and how to code for it.

Now, though, it shouldn’t be hard to control the RGB LED strips through an Arduino, a computer, or even an Android/iOS device with a small IR LED plugged into the headphone jack.

Adafruit has this week announced the arrival of the new Arduino ... of individual RGB LEDs. Compared to NeoPixels, they’ve got great density, power usage and the price-per-LED can’t be beat.

It’s really just an Arduino, RGB LED matrix, and a programmed particle system, but if we’re fascinated by it, it will probably blow an infant’s mind. The idea for this busy box originated ...
