Tutorial: Measure distance with sharp ir sensor with arduino!

The function of this sketch is to obtain the distance from the sharp ir sensor and display it on your computer


Connections from the GP2Y0A21 sharp ir sensor to arduino :

• red wire  → Arduino 5V pin

• black wire →  Arduino GND pin

• yellow wire →  Arduino pin A0

*/

// Include the library:
#include "SharpIR.h"

// Define model and input pin:
#define IRPin A0
#define model 1080

// Create variable to store the distance:
int distance_cm;

/* Model :
 GP2Y0A02YK0F --> 20150
 GP2Y0A21YK0F --> 1080
 GP2Y0A710K0F --> 100500
 GP2YA41SK0F --> 430
*/

// Create a new instance of the SharpIR class:
SharpIR mySensor = SharpIR(IRPin, model);

void setup() {
 // Begin serial communication at a baudrate of 9600:
 Serial.begin(9600);
}

void loop() {
 // Get a distance measurement and store it as distance_cm:
 distance_cm = mySensor.distance();

 // Print the measured distance to the serial monitor:
 Serial.print("Mean distance: ");
 Serial.print(distance_cm);
 Serial.println(" cm");

 delay(1000);
}
