If you’re looking for a way to keep your kitty busy, but would rather not actually have to get up and wave a laser around, this setup allows you to use the Blynk app to turn on and manipulate a laser right from your phone.
Keeping things simple, the enclosure for this project is a yogurt tub, and the laser manipulator is two Arduino-driven servos stuck together with tape. A computer provides power as well as Wi-Fi control, though with a Wi-Fi shield and battery it should be able to be used independently.
