Team Status Report for 3/26

This week, there weren’t any major design changes made. The only change we made was to use the accelerometer off the Arduino Nano directly instead of getting a separate module. Vivian was successfully able to print out the degree change from the horizontal using the accelerometer off the Arduino Nano 33 BLE. This is good because now we won’t have to waste additional pins on the Arduino for an accelerometer.

The most significant risks we see affecting our project right now are the feel of the device and the breath sensor. We plan to mitigate risks on the feel of the device by starting to assemble the physical controller next week, so we’ll have enough time to buy any new components or make any design changes if necessary. For the breath sensor, Vivian has already gone through a couple iterations of prototypes so far, and by doing this we hope to settle on a final configuration that works the best. The sensor works pretty well so far, but at the moment the mounting of the latex barrier has been a bit finicky. Vivian hopes to find a more stable way to mount the barrier next week.

Our schedule hasn’t changed much, but we’re extending integration between the physical controller and RPi through next week. Vivian and Angel have started this integration by sending the data from small buttons to the RPi, but by the end of next week we hope to integrate with real buttons and other sensor data.

The main accomplishment of this week was Angel and Vivian successfully sending a note packet from the Arduino to the RPi. We were able to send this packet with very good accuracy and a pretty short latency. Angel was also able to begin playing some flute sounds off of the RPi using a python library.
