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 ...

Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

7-segment LED displays were revolutionary, finally providing a clear, readable and low-power numerical display solution. We’ve got plenty of other cheap display options now, but sometimes you… ...

Output devices: Motors, solenoids, bulbs, buzzers, relays, LEDs, 7-segment displays. Circuit diagrams show connections. Relays: Electrically operated switches ...

And there you go! A giant 7 segment display made out of glue sticks, easy to control, easy to chain, and while not the most awesome thing ever, I hope it inspires you in your future projects.

Many options exist to drive seven-segment LED displays, but most are limited to low output currents. The approach described here uses one 74ALS374 or 74AS374 octal latch, wired ...
