Prototyping
Hardware
Firstly, we studied and cut the cardboard according to the shape and estimated dimensions of the track car.
Then, we started to assemble those cut pieces to form the cardboard structure as shown at below.
Problem encountered:
Cardboard is too fragile to an extent that some structures of our toy collapsed in the assembly process. But owing to its ease of modification, we still decided to use it.

To ensure that the idea is workable, we remixed some of the online codes and programmed them with Arduino with some electronic components such as 7 segment and buzzer.
Problem encountered:
Once we tested out the codes with each electronic component individually, the Arduino system works perfectly. However, when we connected all electronic components with an Arduino board, the system shut down, and there is no output response. By researching online, we realized the possible reason might be some electronic components such as high torque motor is drawing too much current from the sources, which causes other components to malfunction. Therefore, we added in three battery in parallel with the system to supply it with enough current.
