Description: In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever ...

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.

Nothing reminds us that it’s the holiday season more than an LED Christmas Tree submission. This obviously is not the first of its kind, but [Jose] does offer up a new technique using addressable RGB ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer.

Off the shelf RGB colour pickers allowing you to extract and objects RGB values can range from a few hundred dollars to thousands depending on your needs.
