Power Analysis: Probing WS2812 RGB LEDs
https://www.electronics-lab.com/power-analysis-probing-ws2812-rgb-leds/
Power analysis is a technique to probe the inner workings of an integrated circuit by measuring changes in the supply current. Tim writes: Whenever a logic gate switches, it will cause a tiny current spike that can be measured externally. By inspecting the temporal variation, especially in reaction to an external signal, it is often […]
