What is ws2812

The ws2812 is an intelligent control LED light source, with the control circuit and RGB chip integrated directly into a 5050 RGB LED.

Some features:

• The control circuit and the LED share the only power source.
• Built-in electric reset circuit and power lost reset circuit.
• Each pixel of the three primary color can achieve 256 brightness display, completed 16777216 color full color display, and scan frequency not less than 400Hz/s.
• Cascading port transmission signal by single line.
