1. Introduction Done with tedious mono color backlight? This Grove enables you to set the color to whatever you like via the simple and concise Grove interface. It takes I2C as communication method with your microcontroller. So number of pins required for data exchange and backlight control shrinks from ~10 to 2, relieving IOs for other challenging tasks. Besides, Grove - LCD RGB Backlight supports user-defined characters.

3. Demonstration This demonstration will show you how to use Grove - LCD RGB Backlight, we need a Seeeduino V3.0 else. 3.1 Hardware Installation Hardware installation is very easy, because there's an I2C Grove in Seeeduino, so what we need to do is connect it to I2C Grove via a Grove cable. 3.2 Download Code and Upload You can download the demo code in Github, click here, then extract it to anywhere.
3.3 Change Color of Backlight One of Grove - LCD RGB Backlight's most important feature is: you can change the color backlight, and it's a very simple thing, just use the following function: void setRGB(int r, int g, int b); Then let's try a Red backlight. Modify the code about color into: const int colorR = 255; const int colorG = 0; const int colorB = 0; Upload the code again, woo, see the backlight turn to Red? Then why not try another color? Whatever you like. 3.
