Perhaps you’ve also used them to generate a stable voltage drop because they have a pretty constant voltage across them when current is flowing, but that’s it. Diodes: the shortest Hackaday ...

[Leo] looked at the WS2811 LED driver, but found that the low drive current and the 8-bit PWM output ... just four transistors, a Schottky diode, and a bunch of passives. The other clever bit ...
