PROJ06: IR Laser Pet Toy

Do you want to annoy your (or your family's) pets? Maybe you want to exercise your pet in the laziest way possible? You are going to build a laser pet toy controlled by your IR remote and the Adafruit Metro.

Here's how it's going to work: a cheap-o laser pointer is affixed to the servo horn. You'll mount the servo to your breadboard with double-sided tape to give it a solid base. Then, you'll wire up your infrared sensor along with the servo and code a program that lets you annoy/exercise your pets from a safe distance

What to know about lasers and your pet

The laser pointer dot can drive both cats and dogs towards obsessive behavior because it can seek out the "prey" instinct in your pet. We strongly suggest hiding a few food treats around the room, and then letting the IR Laser Pet Toy move in the direction of the food. Your dog/cat needs to be rewarded for chasing what they consider to be their prey. 

We also advise both you and your pet to avoid any direct eye exposure with the laser. Keep the laser on during play with the animal to avoid them looking at the light (switching it off/turning it on will make them turn around quickly).
