With midterms and all of the craziness leading up to spring break, I’ve been finding lately that all I want is some peace and quiet. That is what inspired my midterm project. My device, “The Librarian” reads in the noise level from an on-board microphone, and if the noise level exceeds the chosen threshold then an alarm and siren go off, to signal that you need to quiet down!
I had expected that the fab lab would have some form of microphone/sound input, but wasn’t able to find any there, and no microphone was included in my Adafruit kit, so I just ordered a microphone that should be coming in next week.
To polish this off and make it midterm ready, I need to integrate the microphone, and create an on screen, web based GUI where the user can set the maximum sound level before triggering the alarm, so that they can set it to their preference.
To be completely honest, there is still a lack of clarity for me on how a lot of the connection stuff works. I understand all of the circuitry, and even the code, but not quite how the networking works. I was able to control padding on a webpage from an analog input, but not quite sure how to turn that around and change something analog from a webpage.
I will need to deepen my understanding on how that works in order to complete this project.
