Hi, I am looking to use a Pi to monitor the rate of crack for a coffee roaster (think popcorn cooking), near the end of the roast it produces high pitched cracks the rate of which I would like to measure in real time as it's a good indicator of when the roast is done.
I'm familiar with Python but not sure where to start with the project, does anyone have any suggestions on extra hardware I'd need or software libraries out there that may might be best suited?
Thanks,
