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.

3.4 With Raspberry Pi

This example will change backlight color and display text. You should connect to GrovePi+ with it like the

following picture.
