Sound Sensor (LM324)

Hi guys I haven't been here a while. :( Long story short, I got a new circuit for you :)


Note:I added the video.

List of Parts
------------------
-Electret Microphone
-LM324 OP-AMP
-Resistors(1kx2,22k,68k,100kx2)
-Capacitors(0,1uf,470uf,22uf,)
-Led

------------------

Here is the schematic

You can feed the op-amp with +5 -5 volt source its a minimum value for this project. You can use +12 -12 voltage maximum.



I will update the post and add a video about the project later :) Ask anything to me with the comment section.

Keep working guys!!!
