While we were trying to use a motor, we realized that the motor was loose, and we were struggling to keep it snug. Then, we realized that there were places for screws to go in the motor to keep it snug. In addition, we programmed the arm to move up and down and noticed that the mistake wasn’t the program itself, however the wires we were using.
Tip of the day: Make sure things are snug in place, and you are sure about what wires are required.
We were struggling to get the arm moving after the reinforcing.
