Is it Possible to recreate a complete Analog circuit on a arduino

Former Member over 13 years ago

Sorry for the Noob question, but

Is it possible to program/recreate a complete analog circuit on a arduino chip

Thanks for any help

Explaining what do you mean by "complete analog circuit" would probably help a lot...

Hi,

Sorry for the vagueness of my original post, the analog circuit I would like to recreate is a metal detector

I don't have the circuit diagram that I want to use but this is a circuit similar to the circuit I was wondering if possible to program a arduino to function like this circuit.

Sorry for the lack of information

Regards

Oh, so possibly the real question here is: "How does one connect or interface an analog circuit to one of the I/O pins of the arduino?"

The answer clearly would be to carefully match the impedance of the two circuits with a not very expensive custom impedance matching circuit. This is not a non-trivial undertaking, even for experts.
