"I Have a Bad Feeling About These Voltage Levels" β‘
C-3PO enters the workshop carrying a 12-LED NeoPixel ring with the careful reverence of someone handling a thermal detonator.
C-3PO: "I want to begin by saying that I have computed no fewer than twenty-three potential failure modes for this particular connection. NeoPixel WS2812B LED rings operate on 5V logic. The Arduino UNO R3 also operates on 5V logic. So far, so excellent. However, should anyone in this workshop be tempted β under any circumstances β to use an ESP32 instead, which operates on 3.3V logic, I must warn them in the strongest possible terms thatβ"
R2-D2 beeps the equivalent of "get on with it."
