Connect an HC-SR04 Range finder as follows:
Spark   HC-SR04
GND     GND
5V      VCC
D1     Trig
D2      Echo

The default usable rangefinder is 10cm to 250cm. Outside of that range -1 is returned as the distance.

You can change this range by supplying two extra parameters to the constructor of minCM and maxCM, like this:

HC_SR04 rangefinder = HC_SR04(trigPin, echoPin, 5.0, 300.0);
