Hi. I am a complete Arduino newbie asking for advice on feasibilty and general guidance on this project:
I’m looking to very finely measure the response time of guitar tuner pedals.
Timing would be triggered by the start of an analog audio signal.
End of timing period would end when the tuning pedal responds by lighting the LED display on the tuner, and this light is measured.
I’m guessing that I’ll need:
A way to get the guitar signal into the Arduino. Guitar cables use 1/4" mono plugs.
A detector that can detect plucking of string (audio signal above a certain threshold?).
A detector that can detect when LED is lit (light above a certain threshold?).
A way to measure the time elapsed between the two events as finely as possible.
Does such a project sound feasible? If so, I’d appreciate really specific guidance on methods, parts and models.
