Using Ancient Litronix DL-1414 LED Displays With an Arduino

Using Ancient Litronix DL-1414 LED Displays With an Arduino

While I was putting together the Tek 492 memory board reader, I though it’d be a nice idea to add a small display. While the Arduino has USB serial I/O, the update rate is fairly pokey and an on-board display can provide more-or-less real time status.

Given that the reader was built for an early-80s memory board, I just had to use a pair of Litronix DL-1414 4-character LED displays from my parts heap.

  1. By an odd coincidence, I was just at that site — I picked up a few DL1414s recently on ebay, and the example code helped with my test rig (I wired mine directly, though, instead ofg through shift registers). They’re really fun little devices, and very stylish!

  2. Anyone know of modern alternative for such displays? I’m working on a watch project and I’m considering using a 4 bit binary display (4 single leds) just because I can’t find a decent thin LED display.

  3. Check out the DL2416 displays. They are pretty pricey, but they have that cool retro look. Here is a link to getting it up and running with an Arduino:
