In this lesson, we will learn how to control WS2812 LED.
5.1 Components used in this course
5.2 Introduction of WS2812 RGB LED
WS2812 RGB module is a low-power RGB tri-color lamp with integrated current
control chip. Its appearance is the same as a 5050LED lamp bead, and each element is
a pixel. The pixel contains an intelligent digital interface data latch signal shaping
amplifier driving circuit, and also contains a high-precision internal oscillator and a
12V high-voltage programmable constant current control part, which effectively
guarantees that the color of the pixel light is highly consistent.
