Help with Sound Sensor

Hey Friends,
Please tell me whether the circuit given in the following link will work or not?
Thank you

If you want to amplify sound it will work. You might want to state what you want to do before asking if it will work.


I want to design a sound sensor and make some lights glow when the sound level crosses a particular intensity.

The circuit you posted will apply AC voltages to the analog input, which could damage the Arduino.

Here is a sound detector board that provides several different outputs (all positive) and can be safely used with the Arduino. SparkFun Sound Detector - SEN-12642 - SparkFun Electronics See the "Hook up Guide" on the product page for instructions.
