Keep cat away from unwanted areas with cat protector

Cats are sneaky pets that don’t like to obey the rules. If you are nearby, then you can keep an eye and chase away. Normally your voice does the trick. But when you are not at home, cats can do what ever they want. Lucky resistor decided to put end to cats domination at home and started a new project called “Cat Protector”. It’s a device which once placed on some area, prevents it from cats visit. Device simply detects cat movement and then speaks recorded phrases with owners voice.

Before building a final product, he first of all made a prototype, to see if this is efficient way to control the cat. After confirming, this works 100%, he finished it with portable enclosure and other elements. “Cat Protector” is based on Arduino Uno. Cat motion is sensed with Panasonic motion sensor AMN32111 which connects to Arduino with three pins. Masters audio is recorded in to SD card which is accessed with Data-Logging shield. Audio is played back through Microchip MCP4821 DAC interfaced to Arduino via SPI. Audio the is amplified on low power amplifier and then played with small 0.2W speaker. There is also a dual color LED used to indicate operation of device. Once built, it can be placed on any surface and hope that cat obeys voice disapproval commands all the time.
