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… ...

Arduino Sketch: Now look at the ‘loopy’ Arduino sketch cooked basically for Uno and Nano editions! /* * Rainbow Flashlight/Tent Light * An RGB LED Multi-Mode Flashlight/Tent Light * Using a Common ...

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 */ ...

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.

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can bu… ...

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’ ...

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 .
