Currently, the greatest risk is that we will not be able to extract usable data from the microphones. If this is because the microphone doesn’t react to any sound input as proven on the oscilloscope (likely incorrectly soldered), we can repeat the assembly/soldering process with more components. If the microphone reacts to oscilloscope testing but not to the microphone testing program that prints to the serial monitor, further microphone testing is required to determine the source of the issue. If the microphone reacts to environment sound but the data we receive does not directly correspond to what we expect, we need to continue signal processing to calibrate the data.
We need to have the hardware aspects mostly complete by Tuesday (the first music testing session of the week) and the webapp subsystem mostly complete by Wednesday (interim demo day).
Since last time, we tested the microphones and LEDs on each board to find out which boards have which functioning. We also tested a program that would change the LED color if the microphone input exceeded a certain threshold. Webapp research about the database and file format continues. Also, we now have a decibel meter! This will provide a baseline against which we can measure the bracelet results.
We haven’t changed the design of the system.
The Gantt chart has been updated:
- The interim demo is now scheduled for Wednesday, April 3rd.
- Database, visualization, customization is due Friday, April 6th.
- Timeliness/accuracy/heat tests are also due April 6th.
Caption: The lights change color to red and back to yellow very fast, so if you want to see it better, change the video speed to 0.25, and focus on 0:02 to 0:04.
