/*
* Ultrasonic Simple
* Prints the distance read by an ultrasonic sensor in
* centimeters. They are supported to four pins ultrasound
* sensors (liek HC-SC04) and three pins (like PING)))
* and Seeed Studio sesores).
*
* The circuit:
* * Module HR-SC04 (four pins) or PING))) (and other with
* three pins), attached to digital pins as follows:
* --------------------- ---------------------
* | HC-SC04 | Arduino | | 3 pins | Arduino |
* --------------------- ---------------------
* | Vcc | 5V | | Vcc | 5V |
* | Trig | 12 | OR | SIG | 13 |
* | Echo | 13 | | Gnd | GND |
* | Gnd | GND | ---------------------
* ---------------------
* Note: You need not obligatorily use the pins defined above
*
* By default, the distance returned by the distanceRead()
* method is in centimeters, to get the distance in inches,
* pass INC as a parameter.
* Example: ultrasonic.distanceRead(INC)
