What did you personally accomplish this week on the project? Give files or photos that demonstrate your progress. Prove to the reader that you put sufficient effort into the project over the course of the week (12+ hours).
This week, I mostly worked on physical aspects of the system. I soldered the 200k resistors to a board (old design) to test mic gain; it’s difficult to tell if the result was an improvement, because oscilloscope/output pin testing was marked by drifting output values and the Beetle or mic overheating. As it turns out, the overheating was likely due to an issue with the mic connections, not resistor values. I also tested if the Beetle could function with battery power alone (not connected to a computer), and got it to respond to pressing the button intended for mode selection. Using https://docs.arduino.cc/built-in-examples/digital/Button/ and Freda’s code from https://courses.ideate.cmu.edu/60-223/f2022/work/date-calc/, I also got the Beetle to respond to a button press by changing state. This will be useful when we need to switch between instantaneous and average mode in the final system.

Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?
Although the deadline of April 24th passed without complete functionality, it should be possible to get everything done by the 30th as promised in the slides.
What deliverables do you hope to complete in the next week?
Since this is due at the end of next week, my overall deliverables are to make sure that the system functions and as many tests are met as possible. More specific deliverables include having a complete and functional file for all integrated code, thresholding the mic output so that LED and transmitted outputs from the mic have some relation to dB values, and helping with remaining tests.
