did someone know a good way to connect an electret to arduino??
i've tried differents ways that i find searching in google, but i think the difficult is the voltaje level, i would like to work with 5 v for the electret supply.
I just finished writing code for using an electret with an Arduino. I posted my code in the topic about music detection. I use a 386 to amplify the signal first and it is just enough, more amplification would be better but would also be more expensive, so I made the code do the work. Let me know if you have any questions about it. Also when I was looking up specs on electret microphones most suggested low voltages around 2V so I used the 3.3V power with a resistor to power it, I don't know what my specific model mine is, it just came with a box of random electronics, but it seems to work well.
You might also consider using this mems-based microphone module from sparkfun: SparkFun Analog MEMS Microphone Breakout - ICS-40180 - BOB-18011 - SparkFun Electronics. This module has the mic mounted and it runs from 3.3V and outputs a 1.65V signal with no audio input. The output will range from 0V to Vdd with loud sounds so it can easily be used with the Arduino ADC.
