After finishing the RGB LED cube, I had some LEDs over and something had to be done with them. After some consideration, I decided to build a clock.
In this project, I designed one common PCB for hour, minute and second panel. 10x10 cm PCB costs almost nothing and that was my size limit. An Arduino Nano is used as the controller.
The clock works as intended. The user can adjust time, color and brightness. First, I thought that a cover over the LEDs is not needed, however it improves the readability.
