Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

The 7-segments LED devices The general principle behind this kind of devices is the same that makes the common LEDs working. To get a LED lighting we should connect its ground pin to the circuit GND ...

For those of us who remember LED calculators, the HP 5082-7400 series red “bubble” displays hold a special charm. Available in 3, 4, or 5-digit varieties, these multiplexed 7-segment displays ...

This modern re-imagining of the turbo button uses an Arduino microcontroller, seven-segment display and tactile switches to emulate the look and feel of the original hardware.

Reddit user Krukerfluk has created an awesome DIY digital clock using 144 x seven segment displays, combining them to create a larger LED display powered by an Arduino Nano.

You can interface this type of display to a microcontroller using one or two output pins. The one-pin MCU interface employs a pulse-width-encoded output per segment.
