Topic: Connect two pin microphone to Uno (Read 1 time) previous topic - next topic


This is a microphone I got from an HP laptop. It has two pins. I want to wire it up with my Arduino Uno board to turn on an LED every time it detects sound above a specified level. I come from programming so I'm familiar with code but I'm new to electronics. Is this possible? If yes, what do I need and how can it be done?


The signal from the microphone will be very low and ideally needs to be amplified. You can buy Arduino modules with a microphone and amplifier (example here) but if you want to make your own then Google "arduino microphone amplifier circuit" to find some examples.
Don't PM me for help as I will ignore it.


Microphones from PC are ALWAYS electret mikes. Look that up on the internet and you will see the additional components you need to make it work.
