He used an Arduino, and multiplexed RGB LEDs with some digital potentiometers to create a color mixing keypad ... Since each axis of the board has eight pins, it’s perfect for the application.

When you need to quantify the color of an object ... or you can buy an off-the-shelf RGB sensor and wire it up to an Arduino. Or you can go back to basics and build this reflective RGB sensor ...

If you’d like to get more specific, Michael Klements’ Arduino-based scanner lets you quantify colors in numerical RGB values via a TCS34725 sensor. User interface for the handheld device is ...

Each addressable LED has an integrated driver that allows you to control the color ... pin. There is so much you can do with WS2812B addressable LEDs once you learn the basics. However, always ...

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’ ...

This one tickles me for some reason - a flame simulation using the Arduino MKR RGB Shield. And that's about it really - all you need is the shield and an Arduino board to plug it directly into, such ...
