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, ...

Sometimes, a good hack is about using less rather than more. That’s the case with this neat tutorial from [Rahul.S] on driving a 7-segment LED display with an FT232. By using this cheap USB to serial ...

The project is utilizing cheap dot LEDs to create a big LED with an interface through SPI and can be expandable for multiple digits with only three wires for receiving data from any microcontroller ...

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 ...

While 7-segment displays are all well and good, they’re considered a bit old hat these days. This project from [Matt Deeds] brings them screaming into the future, though, sporting every color under ...
