In a way, all 7-segment displays are alike; at least from the outside looking in. On the inside it can be quite another story, and that’s certainly the case with the construction of this Soviet-era ...

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 just ...

A common display found on digital watches and readouts that looks like a series of 8s. Each digit is formed by selective illumination of from one to seven separately addressable segments. For more ...

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 ...

The project illustrates a Charlieplexing of a group of 7-segment LED displays which is similar to the Charlieplexing of discrete LEDs but with some changes since all the LED segments have a common pin ...

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, ...
