Post 3-colour LED module (HCMODU0057)
Description
This 3-colour LED module has 3 separate LED inputs (Red, Green and Blue) which can be individually driven by applying a voltage to the appropriate module pin.

PINOUT
PIN 1: RED LED +Ve
PIN 2: GREEN LED +Ve
PIN 3: BLUE LED +Ve
PIN 4: GND

CODE
Code:
/* FILE:    ARD_3_COLOUR_LED_MODULE_Example
   DATE:    04/07/12
   VERSION: 0.1

This is a simple example of how to use the Hobby Components 3 colour LED module.
The module has 3 separate LED inputs (Red, Green & Blue) which can be individually
driven by applying a voltage to the appropriate module pin.
This example uses the standard Arduino analogWrite (PWM) function to cycle
through the full range of colours this module is capable of producing.
Please be aware that the screen print on this module is incorrect. Please see
table below for correct pinout.

PINOUT:

PIN 1: RED LED +Ve
PIN 2: GREEN LED +Ve
PIN 3: BLUE LED +Ve
PIN 4: GND
