This week, I focused on finishing up the arduino interface. I remodeled our pin assignment, since I found a way to use the analog pins provided to manage the trigger pins. As a result, we now have 18 pins in total that we can use, which satisfies our requirement. Furthermore, I was able to finish up the arduino interface and tested on operating 3 sensors and vibrators at the same time.I have concluded our work on arduino for now, and next week, I will focus on the python script in raspberrypi.
