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 ...

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 ...

Not all displays are alike, however, so [Raj] wrote in to show how he used the MAX7219 to control high voltage 7-segment displays.
