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.

Converts HSV to RGB using Arduino code. Controls an RGB LED connected to Arduino pins (typically pins 9, 10, and 11) through PWM to display the color. Includes resistor connections to protect the LED.

In this approach, Arduino is used as the sole framework. It’s typically run using the Arduino IDE or PlatformIO in Arduino-only mode. This is the standard way of running Arduino and focuses ...

[Fjord Carver] brings together an RGB LED and CdS Photoresistor to make a color sensor. Those Cadmium Sulfide lights sensors usually have a very wide swing of resistance when exposed to varying lev… ...

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’ ...
