My robot is now able to move around with the code that I plug into the Arduino. When I began to build, I started out with just the base of the robot, the chassis. I mounted the motors on the chassis. Then, I screwed in the front wheel to the chassis and plugged in the big wheels to the motors. The robot could now stand on its own. I screwed in the battery pack holder on to the top of the chassis and wrapped the wires for the battery holder around in the holes of the chassis, so that they weren’t in the way of anything. The battery pack provides power to the motors. Next came the motor drive. The motor drive is meant to control all aspects of the motor including direction and speed based off the code that is plugged into the Arduino. First, I connected the motors to the motor drive. I had to wrap two wires around the filaments on each motor and connected two wires to the openings on the right and left side of the motor drive, respectively. I then had to connect the battery pack (the power source) to the motor drive. The voltage on the battery pack is 6V, so I could not place the positively charged red wire into the 5V slot, but rather had to place it into the 12V slot of the motor drive. Then, I connected the ground black wire into the Ground slot of the motor drive. Then came the more difficult part. In order to get the motors to run through the motor drive, the motor drive had to be connected and told information by the Arduino. In order to do this, I needed to wire the Arduino to the motor drive. I connected the 5V slot and the Ground slot of the Arduino the the 5V slot and the Ground slot of the motor drive. I already had the ground wire from the battery pack in the ground slot of the motor drive, so I had to make both of these wires fit, which was difficult since I broke a few wires during this process. However, I was finally able to fit both and then had to move on to the actual commands to give to the motor drive. The motor drive has 6 command slots labeled in the following order: ENA, IN1, IN2, IN3, IN4, ENB. These command slots connected to pins of the Arduino. ENA connected to 9, IN1 connected to 7, IN2 connected to 6, IN3 connected to 5, IN4 connected to 4, and ENB connected to 3. Then, I simply plugged in the code I wanted to make the Arduino be able to run seemingly autonomously, and the robot was able to move around.
