A project where an RGB LED connected to an Arduino is controlled based on the color values of the center pixel in an image can be broken down into two main parts: color detection using Python (OpenCV) ...

Resistors used: Red - 82 ohm, Green - 56 ohm, Blue - 56 ohm. Allowing approximately 20 mA to flow through LED. Cathode (-) pins of RGB are connected to 8-bit PWM pins of Arduino for voltage control.

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.
