Introduction
RGB LED module consists of a full-color LED made by R, G, B three pin PWM voltage
input can be adjusted. Primary colors (red/blue / green) strength in order to achieve
full color mixing effect. Control the module with the Arduino can be achieved Cool
lighting effects.

Example
In this example, we blink a LED and using an RGB LED we can generate any color we
want.
Wire connection as below,
“V”-----------5V
“R”-------------------D10
“G”-------------------D11
“B”-------------------D9
