Spaz Cat

Description

For this assignment, I imported an image of a cat I photoshopped into the Processing program, and then created an animated sequence of fast movement.  I then merged the ball code into the image animation code, making it seem in an abstract sense that the cat was chasing the ball.  As the program dictates, the ball increases or decreases in size based on the pressure placed on the FSR.  I also changed the color of the ball as well as the background (reset) to blue.  The FSR is also connected to an LED light.  

Components

1 Arduino-Uno
