VM110N Analogue Input - Monitor a Microphone Signal

Hi All,

First post so be gentle.

I have myself a VM110N and would like to monitor a series of audio ‘beeps’ that come from a device that I cannot connect into and thus will need a microphone to monitor these.

The ‘Beeps’ change frequency but when it becomes a solid Beep (continuous) I plan to action a motor.

Does anyone know a good starting point - A pre-made board maybe that has an inbuilt mic or a jack for a mic? Thought I’d see if there was a solution available before I reinvent the wheel.

Any thoughts and Ideas welcomed.

Thanks…

Any thoughts… Anyone…
