I want to make a microphone myself with the Arduino (capsule=microphone): [![enter image description here][1]][1] I have bought the following as [microphone][2]: As is in the datasheet the microphone operating voltage is between 1.5 and 10 volts. The problem is how do I calculate what resistor do I use to get that voltage? I can't use it as a voltage divider (the resistor with the microphone) right? P.S. I have resistors laying around between 10 \$ \Omega \$ until 10 M\$ \Omega \$ so that won't be a problem. [1]: https://i.sstatic.net/CRAz1.png [2]: http://www.farnell.com/datasheets/1660938.pdf
