Object tracker

Yes the sharp can track my hand at the farther distance than shown in the video.

Code:

#include <Servo.h>
int sharp1 = 0;             // right sensor analogue pin
int sharp2 = 1;            // left sensor analogue pin
int leftdist = 0;           // variable to store left sensor reading
int rightdist = 0;        // variable to store right sensor reading
int headpin = 8;       // pin to which servo is connected
int pos = 90;          // center position for servo

Servo head;      // create a servo object

void setup() {
  head.attach(headpin);
  head.write(pos);         //center the servo
}

void loop() {
  delay(10);
  rightdist = analogRead(sharp1);
  leftdist = analogRead(sharp2);
  if (rightdist < 600 && leftdist < 600) faceforward();
  if (rightdist < 600 && leftdist < 400) faceright();
  if (leftdist < 600 && rightdist < 400) faceleft();
  head.write(pos);
}

void faceright() {
  pos = pos + 1;      //  adding 5 to the servo command(i even tried with 1 instead of 5)
  }
void faceleft() {
  pos = pos - 1;     //  subtracting 5 from the servo command(i even tried with 1 instead of 5)
  }
  void faceforward () {
  head.write(pos);
  }
