Map Function component
The map function is intended to change one range of values into another range of values. For example. Output from a temperature sensor is in centigrade. you can map it to give the result in Fahrenheit. To do that set: InMin to 0, InMax 100, OutMin to 32 & OutMax to 212

Examples
A simple example showing how to take a value from an adc input with the range 0-255 and mapping this to a predetermined range of 50-150 to drive a PWM output.
