This week I worked on adding new features to our app, and continued testing and integration with our temporary sensor when our IMU got fried. We think something might have gone wrong with the seeed studio board power management, because when the IMU got fried, the bluetooth communication also stopped working. I spent hours trying to debug the bluetooth connectivity issue, but ended up making it work only by switching our board to our backup esp32 board. This is important because now we know about this mode of failure for future development and debugging.
For adding the guitar mode, this involved finding a high quality individual guitar note .wave file, then pitching the node higher and lower for a full scale to add to our library. Since our IMU broke and we didn’t have a way to get velocity input, I was able to move forward with implementing the delay between individual notes. I did this by adding a slider to introduce zero to a few milliseconds delay. Since this is already implemented into the code structure, adding the bluetooth input from the IMU should be streamlined.
