Servo Code

// Control a servo motor with a photoresistor

 int servoPin = 2;     // Control pin for servo motor
 int minPulse = 500;   // Minimum servo position
 int maxPulse = 2000;  // Maximum servo position
 int pulse = 0;    

 int analogValue = 0;  // the value returned from the analog sensor
 int analogPin = 0;    // the analog pin that the sensor's on

 void setup() {
  pinMode(servoPin, OUTPUT);  // Set servo pin as an output pin
  pulse = minPulse;           // Set the motor position value to the minimum
  Serial.begin(9600);
 }

void loop() {
  analogValue = analogRead(analogPin);   
  pulse = map(analogValue,600,1023,minPulse,maxPulse);
  analogWrite(servoPin, pulse);
