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.

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 ...

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 ...

As you might expect, there’s an Arduino and some RGB LED strips involved. But the key to this build is in the 16 pieces of side-glow plastic fiber optic tubing.

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.

Official Arduino Example Tutorials: The Arduino computer software is loaded with tons of examples for you to use in your own code or to run through as a learning experience.

Adafruit's PioMatter library adds HUB75 RGB LED Matrix support to the Raspberry Pi 5 using PIOs (Programmable I/Os) on the RP1 chipset.
