Team Status Report For 2/19

This week we analyzed the feedback from our proposal presentation and finalized the majority of the design decisions regarding the controller. The most important piece of feedback was regarding the realism and implementation of the breath control mechanism, as it is a crucial component of learning the flute as a beginner. We found another way to implement this without a microphone: using a latex balloon, photodiode, and an LED that would only work if the user is blowing correctly. We also lengthened the Gantt chart and reduced our slack since we have not been able to do much without the physical components we need. In response to the feedback, we also decided to halve the latency requirement as we are confident it can be met given the Baud Rate of Bluetooth. We received our Arduino and Raspberry Pi and finished ordering most of our other components. 

The most significant risk we see ourselves facing is the connection between our Raspberry Pi and web application. Our current plan is for the Raspberry Pi to write to a text file to communicate with the web app. The backup plan if this doesn’t work is to create the visuals using Tkinter (the Python graphics library). We should test this communication early next week, to be able to switch to our backup plan as soon as possible.
