Here is another clever circuit that will create cool effects for a large array of smart pixels.
Low cost circuitry
Easy to built and implement
No fancy bitbanging and worrying about timing constrains
Utilize any WS2811 based controller for RGB Lighting (Single Wire SPI)
Objective: This circuit converts a 12V common anode biased RGB (or single color) module to a smart node with simple and low cost components.
Interface allows color control of individual RGB modules and control of many pixels via common WS2811 based controllers. (512 colors)
The 4-wire RGB+...
