/* *************  L3Dnam - may2015  ****************** 
This sketch demonstrate how to use PNG images from a gauge and an arrow, to make a fully functional
"real like" Gauge responding for the Mouse-X movement, showing angles for a Servo position (0º to 180º) 
for example!  Need 2 PNG images on Data subFolder inside the Sketch folder.
Marshall B&P gauge.png  and  marshall B&P ponteiro.png. -->  Both images must have no Background.
Create your own png images from real gauges or Other Objetcs and Enjoy.
