Pseudo-randomly moves a servo tower (on X and Y axis) and lights up a laser.
Watch it working : https://www.youtube.com/watch?v=hHIrxL0giJQ
x_servo is attached to pin 9 (and +5V and GND) and moves in the X plan.
y_servo is attached to pin 6 (and +5V and GND) and moves in the Y plan.
Laser is attached to pin 13 (and GND).
Download the .ino file, open it inside the arduino software and send it to your arduino.
The program randomly choose a new position for the laser inside a square you can define in the variables. It checks the new position is different from the old one of at least "minimal_movement". It moves the tower to the new position and stays still for a time between min_freeze and max_freeze (this aims to reproduce the behaviour of an insect landing somewhere for a bit and then flying off, that's the variable you need to increase if your cat is fat...). Ans starts the process over and over again.
