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.
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.
