Tri-Lasers for Felines @Raspberry_Pi #PiDay #RaspberryPi
from enzo via hackster.io
The aim is to entertain cat(s) with a moving laser game. it activates when the cat is around, and in case of attack, it shut down!
The device remains in stand by until the cat presence is detected by the PIR sensor.
1- Then the lasers are activated (by the code which can select one, two or all the lasers or random selections).
2- The laser lights perform randoms trajectories thanks to the two servo motors (the speed of the movement, and the vertical and horizontal range can be defined by python code).
3- The activity keeps on until the cat is detected by the PIR sensor. Every minutes it checks the presence. The waiting time can be increased or reduced by the code.
4- Every time the sensor is triggered an entry is created on the application logs, which allow to monitor the cat’s activity during our absence.
5- In addition, in case the cat reaches and start to play with the device, a tilt sensor detects the activity and it reduces the risk of damage by stopping the device.
