Getting Started
This getting started will show you how to use Grove - LCD RGB Backlight, we need a Seeeduino as well.
!!!Note This demo is under Win10 and Arduino IDE1.6.9.
STEP1. Download Arduino Library
You need to download the library and install to your Arduino IDE.
Please follow how to install an arduino library procedures to install LCD RGB Backlight library.
STEP2. Hardware Installation
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.
STEP3. Download Code and Upload
You can download the demo code in Github, click here, then extract it to anywhere.
If you have some problem with this step, please refer to Getting Start with Seeeduino 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.
STEP4. 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:
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.
