A large 7-segment LED display that’s visible in the glare of his bench lighting and not just in subdued illumination. Future plans include replacing the messy wiring with stripboard sections for ...

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 ...

When [Rodrigo Feliciano] realized that the reason his seven-segment LED wall clock wasn’t working was because the original TG1508D5V5 controller was fried, he had a decision to make.

The next step would be to add it all up to see the usage duty cycle for a given segment over all digits. For example, by adding up the “on” designations (segment set to “1”) in the table (Figure 3 ), ...

Seven-segment Display Using two seven-segment digits, this readout can display from 00 to 99. Each of the seven segments has its own contact to the outside electronics.

In addition to coming in white and blue colors, this seven-segment LED display and bargraph employs a contrasting black face color that enhances the white and blue light output.

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 ...
