This project features a custom ATmega328P microcontroller board programmed in C. It drives a 4-digit 7-segment display to implement a simple counter application. Arduino based clock that syncronizes ...

In what might be a wonderful tribute to that, [Davide Gironi] created a simple AVR-powered 16-digit serial display. It can display two numbers, and that’s it. A MAX7219 drives the display ...

On the inside it can be quite another story, and that’s certainly the case with the construction of this Soviet-era 7-segment numerical display. From the outside it may look a bit sturdier than ...
