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

********Code begin********
