We never did crack open our Etch-a-Sketch, but we did scrape out a window large enough to really check out the mechanism inside. [MrLangford] is bringing the Etch-a-Sketch into the 21st century whi… ...

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. ... Arduino Sketch Code /* Arduino Color Wand -RGB LED */ ...

This time around it’s an Arduino ... 11 thoughts on “ Color Sensing With An RGB LED And ... with 3 LEDs. Try breadboarding one up, it only takes 5 minutes. I put up a processing sketch ...

Infineon's RGB LED Lighting Shield is one two of Arduino-based evaluation boards created to showcase the capabilities of its ARM-based XMC1000 MCUs in lighting and motor control applications. Unlike ...

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.

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 .

For prototyping, Infineon has a RGB LED lighting control shield for Arduino, based around its ARM Cortex-M0 XMC1202 microcontroller. On board is something called a ‘brightness colour control unit’ ...
