thingiverse

This DIY project combines art and technology to create a unique gift, a beautiful addition to any room. An Arduino-controlled RGB LED coaster uses Keyes RGB LEDs in a simple design, resulting in a colorful display that responds to music or lights up in sync with ambient lighting conditions. The source code can be found on the project's GitHub page. On YouTube, a tutorial shows how to set it all up, complete with necessary circuit diagrams and other useful resources.
