Eye Movement code

[chichi8]

Anyone want to modify this code for me? What it does right now is use two servos to move an eye around randomly. I want to modify it so that using a motion sensor, one servo controls the eye moving randomly back and forth, and the other servo controls the eyelid opening when it senses movement, and closing when there's no more movement. So the eye servo would still be random, but the eyelid servo would go from 0 to 180 when there's movement, then back from 180 to 0 after a few seconds of no movement.

#include <Servo.h> //include servo library for servo control


Servo horServo; //servo for left/right movement
Servo vertServo; //servo for up/down movement


byte randomhor; //define random horizontal position variable
byte randomvert; //define random vertical position variable
int randomdelay; //define random delay variable


#define HLEFTLIMIT 0 //define left limit on horizontal (left/right) servo
#define HRIGHTLIMIT 180 //define right limit on horizontal (left/right) servo


#define VTOPLIMIT 60 //define top limit on vertical (up/down) servo
#define VBOTLIMIT 180 //define bottom limit on horizontal (up/down) servo




void setup()
{
  horServo.attach(4); //horizontal servo on pin 8
  vertServo.attach(5); //vertical servo on pin 9
  randomSeed(analogRead(0)); //Create some random values using an unconnected analog pin
}




void loop()
{
  randomhor = random(HLEFTLIMIT, HRIGHTLIMIT); //set limits
  randomvert = random(VTOPLIMIT, VBOTLIMIT); //set limits
  randomdelay = random(1000, 4000); //moves every 1 to 4 seconds
 
  horServo.write(randomhor); //write to the horizontal servo
  vertServo.write(randomvert); //write to the vertical servo
  delay(randomdelay); //delay a random amount of time (within values set above)
}

What sort of movement? Where and at what range? What device do you intend to use to detect this movement? Do you already have the device? I can't see any sign of it in the code.
