Smart Laser Pointer for Pets – Interactive Toy for Animals Introduction

Want to keep your cat (or curious dog) entertained without manually moving the laser pointer? The Smart Laser Pointer for Pets is the perfect solution! This automatic device moves the laser randomly using two servo motors controlled by an Arduino Nano, stimulating your pet’s hunting instincts and keeping them active, fit, and mentally engaged.

Designed to be compact, easy to print, and simple to assemble, this toy is perfect for DIY enthusiasts who want to create an interactive experience for their pets.

How does it work?

At the core of this project is an Arduino Nano, which controls two servo motors to move the laser across two axes, creating random patterns that keep pets engaged. The algorithm can be customized in the code to modify laser behavior, adjusting speed, movement angles, and trajectories.

The laser pointer is powered by a 5V 1A/2A power supply, making it flexible and easy to use in different environments.
