Self made microphone burns arduino
I did this a very long time ago, so I might forget something. However, I'm almost completely sure I used resistors in the Kohm range.

After googling a bit I found this post, which might help you get a better understanding of how to use your microhpone.

However, I have noticed you intend to connect your microphone to the analog input of an Arduino. So remember to polarize the analog output to around 2.5V (maybe employing an Operational AMplifier to avoid distortion?) in order to avoid loosing part of your signal (if it is too close to 0V or 5V).



I have checked the circuit you provided. Indeed, it uses 10Kohm and 4.7Kohm to polarize the microphone.

That is, your Arduino gets fried because the 10ohm resistor draws relatively high currents (in the order of 500mA) which Arduino is not designed to handle.

I'm sure that once you replace your resistor your circuit will work fine :) Good luck!
