Hi i am currently working on a project where i have to make a circuit which can detect sound.most preferably is used under a class room which i can detect the noise levels and send the signals into 8051 micro controller and display a message "the noise level is too high" onto lcd display.
I wonder if any peeps out there who can help me with my circuit?
Thanks
