This week, I rebuilt and confirmed my proof of concept works and that the Arduino is able to detect the magnet approaching hall effect sensors. I built the system with 8 sensors, and all eight of them were able to send the signal to the Arduino, and I could see the correct output on the serial monitor. I also finished soldering the mainboard of the system.
Next week, my plan is to finish soldering the sensors, finish testing the soldering, and the installation of magnets onto the saxophone. I am currently still behind the schedule, but I have caught up compared to last week’s progress. I will put more time this week to push the construction progress as far as possible.
