This week, I mainly focused on testing the system together with kelton, and made sure that connections between the arduino and the raspberry pi were working as expected. So far, the interface seems fine and we would need to move on to more testing to make sure that our threat detection are working correctly. I also started making physical models and developed circuit connection schemes that we will carry on next week. Moving on, we will start to assemble our physical belt together first, and conduct software testing from that point onward.
