Robotics day 14-keypad robot

We had to download a particular library from the Arduino IDE on the fourteenth day of course. The components required to control the rows and columns of each segment were already included in this. We used the 4x4 keypad, which was its most basic model. This was a simple component of the class that required us to download the sketch library from the MacBook. More information about the robot's controls will be covered in the following lesson.
