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.

One more suggestion: if we use an Arduino PWM pin as the common anode pin, we can power on/off the display and change its brightness. What if using Common Cathode Display. If we put in the sockets ...

If you’ve ever wanted to make your own VU meter but were scared off by the signal process you need to study this tutorial. Hackaday Alum [Phil Burgess] developed the device using an RGB LED m… ...

The earliest televisions used a spinning disk technology called the Nipkow disk, which is exactly what [Science ‘n’ Stuff] recreated with their Arduino-based mechanical color television… ...
