The Remote Control Transceiver (RMT) on the ESP32 is a special hardware module that allows precise generation and reception of timing signals such as IR and RF control. Here I will show how to run it and use it to operate the WS2812B diodes, which are known to need a fairly precise waveform at the DI input to obtain colour data. By the way, we will look at the generated waveforms on an oscilloscope.

To begin with, I will remind you of the previous topics in the series. The first, most important discussion of the WS2812 and similar:
