<syntaxhighlight lang="C++" line>

1. include "Ultrasonic.h"

Ultrasonic ultrasonic(5); void setup() {

 Serial.begin(9600);

} void loop() {

 long RangeCm;
 long RangeInch;
 Serial.println("Range, cm: ");
 RangeCm = ultrasonic.MeasureInCentimeters();
 Serial.print(RangeCm);
 Serial.println(" cm");
 delay(250);

 RangeInch = ultrasonic.MeasureInInches();
 Serial.println("Range, inch: ");

1. Connect the Grove Ultrasonic Ranger to digital port D4

ultrasonic_ranger = 4

while True:

   try:
       # Read distance value from Ultrasonic
       print ultrasonicRead(ultrasonic_ranger)

   except TypeError:
