In Project 4, We need Servo Motor and Potentiometer to work. I have start the Servo Motor to do a testing since I was not able to use the header pin . So, I had to use jumper wire to use Servo Motor to test it. I was able to test it and became to work. Once I test it without breadboard it was good. Then I needed do on breadboard to connected it good as well 3 needed 3 jumper wire for Servo Motor to connected since there is no hook up connections towed it. The Servo Motor has red, yellow, brown wire to jumper cable wire to work in my testing stage and ran program to see if the Servo spins around. After the testing stage , I was able connected to Potentiometer to analog line with jumper cable and Servo Motor in Digital line. They needed send it to different line to make it work. I also needed + and – wires to work with controller board on 5V and GRD, I had to connect them on those to work. I also needed to program Servo Motor and Potentiometer to make connections. After I programed them I was able to turn the Potentiometer and the Servo Motor spins around .
