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 ...

Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced circuits using multiple seven-segment light emitting diode displays. Here is a simple, yet useful ...

Of course, there’s nothing unusual about using 7-segment displays, especially in a clock ... a 3D-printed case and an Arduino Nano coupled with a DS1307 make the clock part work.
