Check out how to create a unique Mechanical 7 Segment Display using cardboard! In this video, we unveil a one-of-a-kind mechanism that we've invented, featuring 7 circles each with its own trigger.

And we end up seeing all kinds of display techniques being used to show time. For the simplest of builds, 7-segment display modules usually get dug up from the parts bin.

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...
