/*
Press to Servo

Controlling a servo position using a pressure sensor (variable resistor) 

Circuit:
Connect servo to positive and negative and the yellow cable to digital 9;
Attach the pressure sensor to positive on the short leg, negative on the 
end of the resistor and data cable to analog pin 1 and the area between 
the resistor and the sensor.
