This video was taken after we finished the initial layout of our product, and there were some circuitry logistics I was confused about. In order to connect two motors to one battery pack, there must be two negative circuits to connect to each motor, however, the battery pack only had one. I discovered this by observing the diagram above on how to create a circuit with a switch and two motors.

Mr. Hussack helped us build a small prototype of the circuit to test if the circuit would actually work, and the concept was plausible with the materials provided. In the video, it could be observed that the circuit does indeed work, but requires tying two negative circuits with the battery pack negative circuit in order to have enough for the two motors. In conclusion, the prototype circuit was a massive success and gave us the green light to move forward without any worries about circuitry. However, this new discovery meant that there was an increased amount of parts to solder, as I needed to solder the circuits together to ensure that they were secure and electricity could flow well throughout the circuit.

It was actually Hajin’s suggestion to solder all the circuits together after he saw the prototype where we tied the wires of circuits together to connect them. He thought that soldering would not only make the circuit more stable but it also increased the neatness and aesthetic appeal of our product. Discovering that we need a new circuit system completely changed how our product looks on the backside, making it vastly different from the initial sketch we had beforehand, however, this could also be seen as an improvement to the string launcher since now the circuit is actually possible.
