Arduino Assignment 2

// For this projct I got this code from https://toptechboy.com/arduino-tutorial-39-using-a-joystick-to-control-dc-motor-speed-and-direction/. Paul McWhorter is the man who wrote the article.
//For this project I used 3,4, and 5 on the digital pins side. I also used pin A1 on the Analog side along with the 5 volt and the gnd on the power side.
