A display decoder is used to convert a BCD or a binary code into a 7 segment code used to operate a 7 segment LED display. Here we design a simple display decoder circuit using logic gates. A display ...

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 ...

I'm using dual 7-segment LED displays in another project, but I figured I could have designed that using fewer GPIO pins than I did. So I tried out my theory here. Now, first things first. You would ...

This project is intended to bring a simple, traditional-looking LED 7-Segment desk clock into the 21st century by using simple network time protocol to obtain the correct time. It was born out of ...

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 as a shift register, ...

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 provided ...
