Zu viele LED anzusteuern und zu wenige Ausgänge am Controller übrig? #Charlieplexing kann eine Lösung sein https://dd3ah.de/charlieplexing/
Charlieplexing LEDs is actually really neat, if you understand how it works. It's basically just a LED matrix where you use the same pins on both sides of the matrix. I've written about it in my latest blog post: https://aykevl.nl/2026/01/c

What “charlieplexing” means
WikipediaCharlieplexing is a technique for accessing a large number of LEDs, switches, micro-capacitors or other I/O entities, using relatively few tri-state logic wires from a microcontroller. These I/O entities can be wired as discrete components, x/y arrays, or woven in a diagonally intersecting pattern to form diagonal arrays.

every network with a public tag surfaceFollow #charlieplexing straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.
Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/charlieplexing
