			The Arduino Code

			<syntaxhighlight lang="c">

			#include <Wire.h>



			void setup()

			{

			Wire.begin(); // join i2c bus (address optional for master)

			Serial.begin(9600); // start serial communication at 9600bps

			}



			int reading = 0;

			int count=0;

			char buf[3];



			void loop()

			{

			// step 3: instruct sensor to return a particular echo reading

			Wire.beginTransmission(0x0a);

			Wire.write(byte(0x4c)); // sets register pointer to echo #1 register (0x02)

			Wire.endTransmission(false); // stop transmitting

			// step 4: request reading from sensor

			Wire.requestFrom(0x0a, 32); // request 2 bytes from slave device #112



			// step 5: receive reading from sensor

			count=0;

			while(count<32)

			{

			if(2 <= Wire.available()) // if two bytes were received

			{

			reading = Wire.read(); // receive high byte (overwrites previous reading)

			reading+= Wire.read()<<8;

			Serial.print(reading); // print the reading

			Serial.print(" ");

			count+=2;

			}

			}
			//while(Wire.available()<1);
			//reading = Wire.read();

			Serial.println();

			}
