Peter Drescher / Mbed 2 deprecated app-board-RGB2

Example program to cycle the RGB LED on the mbed application board through all colours

Dependencies:   C12832_lcd LCD_fonts mbed

Fork of app-board-RGB by Chris Styles

Test Program to show the RGB Led on the mbed Lab Board

The color is changed by Pot 2, the value by Pot 1.

The program use a function to convert hue , saturation and value to RGB.

With this parameters you can change the color thru the rainbow. see http://en.wikipedia.org/wiki/HSL_and_HSV
