A new publication from Opto-Electronic Science; DOI 10.29026/oes.2023.230005 overviews how GaN-based LED achieves high rate Wavelength division multiplexing visible light communication system with ...

“Charlieplexing” as a method of multiplexing LED displays has recently attracted a lot of attention because it allows you, with N I/Olines, to control N×(N–1) LEDs (reference 1 through reference 5).

While regular Hackaday readers already know how to blink a LED with a microcontroller and have moved onto slightly more challenging projects such as solving the Navier-Stokes equations in 6502 ...

We usually stay within the recommended Amperage with LEDs, but multiplexed displays provide an interesting opportunity to push them outside of that range. Because multiplexing scans a set of LEDs, ...
