I'm new to Arduino and programming so I'm a bit overwhelmed by the volume and variety of stuff here haha.
For a project I'm looking for the necessary sensors/opamps needed to trigger frequency dependant actions. So say a low frequency of say 90hz picked up by the mic sensor would trigger x while a higher frequency of say 12k would trigger y.
The majority of microphones I found are just voltage dependant (=volume) and not frequency based. I have the explore IoT Kit.
Also are there any codes regarding this type of project I could use as a basis?
Thanks a ton guys!
