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. Want to get a love heart or some other foreign characters? Just take advantage of this feature and design it! This product is a replacement of Grove - Serial LCD. If you are looking for primitive 16x2 LCD modules, we have green yellow backlight version and blue backlight version on sale also.

!!!Note This demo is under Win10 and Arduino IDE1.6.9.
You need to download the library and install to your Arduino IDE.
Hardware installation is very easy, because there's an I2C Grove in Seeeduino, so what we need to do is to connect it to I2C Grove via a Grove cable.
!!!Note Please select 5v via the toggle switch on Seeeduino V4.2, otherwise the Grove - LCD RGB Backlight may not function properly.
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:
Then let's try a Red backlight. Modify the code about color into:
Upload the code again, woo, see the backlight turn to Red? Then why not try another color? Whatever you like.
This getting started will show you how to use Grove - LCD RGB Backlight, we need a as well.
Please follow procedures to install LCD RGB Backlight library.
You can download the demo code in Github, click , then extract it to anywhere.
If you have some problem with this step, please refer to there is a Hello World example in the library, open it, and upload to Seeeduino V4.2. Then you can see "Hello world" on the first row, and second row will print the number of second since reset.
