// Test the Ultrasound Sensor
// 
// We are using port S5 on the Duinobot board 
//
//  NOTES: 
//      - Ports S0-S5 are analog input pins
//      - S0 is identical to Arduino A0 and so on (S5=A5)
//      - To use these ports as Digital pins add 14
//

// we are using the ping library to interact with the sensor
#include <Ping.h>

// setup the sensor on analog A5 (this is also S5)
PingSensor ping(A5); //S5 input.
