Typically bit-banging an I/O line is the common method of driving the WS2812B (WS2811) RGB LEDs. However, this ties up precious microcontroller cycles while it waits around to flip a bit. A less ...
For how often the Raspberry Pi is used as a media server, and how easy it is to connect a bunch of LEDs to the GPIO pins on the Pi, we’re surprised we haven’t seen something like Hyperion before. It ...
