How to Control Addressable LED Strips via USB! (WS2811/WS2812b PC App Control)
Want to control your addressable LED strips directly from a PC?
In this video, we test a custom USB-to-I2C/SPI/1Wire adapter paired with a dedicated PC application to drive WS2811, WS2812b, WS2813, WS2815, and WS2818 LED strips!
Watch how the software generates a color frame array (3 bytes per LED for R, G, B) and transfers data frame-by-frame via USB.
We’ll also look at how changing color steps affects the color-shifting speed and brightness.
