Bonjour,
Je suis tout nouveau et j'essai de réaliser un laser pour que mon chat me laisse tranquille ! 
J'ai récupérer le code sur un site et je souhaiterais y ajouter un shutdown pour que le laser cesse de fonctionner au bout de 5min par exemple (il va devenir fou sinon ...).
J'ai commencé à lire plusieurs sujets/tuto la dessus et j'avoue être perdu entre les timer/delay (en même temps c'est ma première réalisation).
Est ce qu'une âme charitable peut m'aider ? 
merci !
Mon bout de code ressemble à cela:
#include <Servo.h>
float min_x = 5;
float max_x = 50;
float min_y = 5;
float max_y = 50;
int min_freeze = 100;
int max_freeze = 500;
float minimal_movement = 0;
/* YOU SHOULD NOT HAVE TO MODIFY THE CODE BELOW THIS LINE */
// finding center of square for starting point
int random_delay;
float x_position = min_x + (max_x - min_x) / 2;
float y_position = min_y + (max_y - min_y) / 2;
float x_old_position = x_position;
float y_old_position = y_position;
float x_new_position;
float y_new_position;
float x_speed;
float y_speed;
int movement_time;
// Instantiating two servos
Servo x_servo;
Servo y_servo;
int pos = 0;
void setup() {
y_servo.attach(6); // attaches the y servo on pin 6 to the servo object
x_servo.attach(9); // attaches the x servo on pin 9 to the servo object
pinMode (13, OUTPUT);
digitalWrite (13, HIGH); // switch on the laser
//Place the servos in the center at the beginning
y_servo.write(y_position);
x_servo.write(x_position);
}
void loop() {
movement_time = random(10, 40);
random_delay = random(min_freeze, max_freeze);
x_new_position = random(min_x + minimal_movement, max_x - minimal_movement);
y_new_position = random(min_y + minimal_movement, max_y - minimal_movement);
if ( (y_new_position > y_old_position) && (abs(y_new_position - y_old_position) < 5 )) {
y_new_position = y_new_position + minimal_movement;
} else if ( (y_new_position < y_old_position) && (abs(y_new_position - y_old_position) < 5 )) {
y_new_position = y_new_position - minimal_movement;
}
if ( (x_new_position > x_old_position) && (abs(x_new_position - x_old_position) < 5 )) {
x_new_position = x_new_position + minimal_movement;
} else if ( (x_new_position < x_old_position) && (abs(x_new_position - x_old_position) < 5 )) {
x_new_position = x_new_position - minimal_movement;
}
x_speed = (x_new_position - x_old_position) / movement_time;
y_speed = (y_new_position - y_old_position) / movement_time;
for (pos = 0; pos < movement_time; pos += 1) {
x_position = x_position + x_speed;
y_position = y_position + y_speed;
x_servo.write(x_position);
y_servo.write(y_position);
delay(10);
}
x_old_position = x_new_position;
y_old_position = y_new_position;
delay(random_delay);
}
