Pseudo-randomly moves a servo tower (on X and Y axis) and lights up a laser. Re-written into Python in order to support Circuit Python.
Watch the original working : https://www.youtube.com/watch?v=hHIrxL0giJQ
- x_servo is attached to pin 12 (and +5V and GND) and moves in the X plane
- y_servo is attached to pin 11 (and +5V and GND) and moves in the Y plane
- Laser is attached to pin 13 (and GND)
Download the code.py file, copy it to a board that runs Circuit Python, and reset the board.
The program randomly choose a new position for the laser inside a square you can define in the variables. It verifies the new position is different from the old one by 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...) and starts the process over and over again.
