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.

This is a tiny and clearly arranged Arduino library for the basic RGB LED functions, to easily drive an RGB color LED (common anode/common cathode) and mix the colors. It uses the principle of ...

Here we describe an open-source Arduino RGB LED photometer that can be 3D printed and contains an educational interface written in Python for use in chemistry laboratories. In addition, the CAD models ...

You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy an off-the-shelf RGB sensor and wire it up to an Arduino.

How to Use Connect the RGB LED to Arduino pins with resistors according to the wiring diagram. Upload the provided Arduino code (hsvtorgb.ino) to your Arduino board. Open the serial monitor and input ...

Neopixels, or WS2812Bs, are addressable RGB LEDs , which can be controlled individually by a microcontroller, in this case, an Arduino.
