This example shows you how to read analog input from the physical world using a potentiometer. Apotentiometeris a simple mechanical device that provides a varying amount of resistance when its shaft is turned. By passing voltage through a potentiometer and into an analog input on your board, it...

Analog read produces a value of 0-1023, equating to 0v to 5v. "((long)sensorValue * 5000 / 1024)" is the voltage on the sensor's output in millivolts. There's a 500mv offset to subtract. The unit produces 133mv per amp of current, so ...
