Costumes are mandatory! So, as part of my costume, I have gotten the idea into my head that I'd like to build a wearable, battery-powered, 8-character alphanumeric display using 14-segment LEDs. I'm ...

We’re not sure, but the number of recognizable alphanumeric characters that a seven-segment display can manage seems to have more to do with human pattern recognition than engineering. It takes some ...

It’s interesting what you see when you train a black light on everyday objects. We strongly suggest not doing this in a hotel room, but if you shine UV light on, say, a printed circuit board, you ...

For mission-critical applications, the BD Blue series blue 1" seven-segment display relies on dual-chip redundancy for improved reliability and uniformity. The display is available in a range of ...

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 ...

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 ...
