Hey guys, I am new to the Arduino programming and here I have an urgent question about the sound location algorithm. For now, I am trying to use three microphones with Arduino UNO to locate the source of an acoustic impulse.
Three microphones are placed at 120 degrees each and there is a servo in the middle of that. When an impulse comes, the servo should point to the direction of the sound from
I really need the source code to calculate the turning angle of servo based on the three inputs of microphones. For now, I am using the analog read to compare the values of three inputs. But it did not work.
Really appreciate for any guidance.
What did you find on Google? Why do the existing algorithms not work for you?
Do you know how precisely you need to measure the impulse arrival time? Have you checked if the Arduino can measure intervals that small?
When's your assignment due?
Post your code, in code tags - How to post code properly.

For now, I am using the analog read to compare the values of three inputs. But it did not work.
Figure out, or look up how long it takes analogRead() to make three successive measurements, and calculate how far a sound wavefront will travel in that time.
Compare that with the dimensions of your microphone setup and let us know what you conclude.
