Today, following up from yesterday, I plan to finish the wiring work and check whether the motors and limit switches are functioning properly. First, I roughly considered the placement of the motor drivers, the Arduino, and the speaker amplifier. Then, I drilled holes to secure each driver in its designated position. For boards like the Arduino or the speaker amplifier that have pins protruding from the back, I inserted a nut in the middle to adjust the spacing.

I positioned the breadboard in between. Connections that could be made directly to the Arduino board were connected directly, while those that could not were routed through the breadboard. Each board was placed according to an appropriate layout. Since two motors need to operate, I modified the code to accommodate both. There were no major changes; essentially, I just doubled everything where needed, but I avoided unnecessary multiplication where optimization was not required.

I had planned to connect the speakers today as well, but rather than focusing on whether sound comes out, the important aspect is how the volume changes depending on the speaker’s position. Therefore, I will connect the speakers after completing the relevant code. In addition, it is time to start selecting the sounds that will go into the prototype.

This prototype focuses on the type of conflict between the individual and society, so I will likely extract sounds from news sources or similar materials, focusing on something like a solo protest.
