![]() I thought I could make a sensor setup that detected sound, and would alert you if there was a loud noise. ![]() ![]() That’s when I was struck with new inspiration, partly from a video I watched of cameras people had installed to watch their pets inside their homes. Program was letting me know which mics heard a noise + the time at which they heard it.) I ran into a bunch of headaches with the math as well, but I need a longer distance between the mics to get that to work! (Following pictures show mic circuit, along with the sample output of the program. The knock sensors weren’t sensitive enough for my needs! I turned to microphones, but discovered that millisecond timing wasn’t going to be good enough to triangulate sound. I had planned to create the first step in that, simply detecting sound and locating the source. At first, I was inspired to create a triangulation system, mostly because I saw knock sensors and thought it’d be really cool to have a robot that figures out where a sound is coming from and navigates to it.
