Arduino development (II)_ RGB light control method based on Arduino uno development board

Arduino Development （ Two ）_ be based on Arduino UNO Development board RGB Lighting control method

First , Let's take a look Arduino UNO The specific pin arrangement of the development board , As shown in the figure below ,

Learn more about Tricolor RGB LED modular , As shown in the figure below ,

Three primary colors are red 、 green 、 blue , So we can combine these three colors , Realize the display of different colors , It can be seen from the figure below ： Red （255,0,0）, green （0,255,0）, Blue （0,0,255）
