Programming was written to the Arduinos. This was not a significant task but finding suitable data cables that could pass through the opening was much harder. Many of the micro USB cables in my stock are only power, not data. Some cables were ordered specifically for this project but they were inadvertently power-only cables.


Adding the program to the Raspberry Pi Zeros should have been an easy task but the wrong OS was downloaded for the computers and I didn't want to learn the finer points of running all the necessary commands through a command prompt. An updated GUI OS will have to be put onto the memory cards.
