"Wackcoon" is designed to detect and repel animal pests from backyards. This project:

• uses Node.js, Raspberry Pi, Raspbian, Linux, and Microsoft Cognitive Services, etc.
• takes pictures in intervals of 10 seconds
• uses a camera and infrared sensor to detect raccoon movement at night
• compares each picture taken to the one before it
• checks to see how close of a resemblance there is, as a diff file

If, and only if, there is a significant difference noticed between two pictures, we use cognitive services vision API to look for an animal (specifically a raccoon). A confidence percentage of 90% or more triggers a buzzer to scare away the pest from the yard.
