/*
This code should be pasted within the files where this function is needed.
This function will not create any code conflicts.
The function call is similar to printf: ardprintf("Test %d %s", 25, "string");
To print the '%' character, use '%%'
This code was first posted on http://arduino.stackexchange.com/a/201
