Hi, i was just wondering if anyone on here could help me.
I'm looking to do a basic guitar tuning circuit for my a-level coursework in electronics, and have got the basic idea on how it would be done, i'm just a bit stuck with a few details. I want to basically plug the guitar in, and the circuit to get the frequency and compare it with what the frequency should be (possibly using the resonant frequency of a tuned circuit?) and then to implement a comparator to determine whether to light the flat or sharp LED. What i'm not sure about is how I'd convert the frequency input to a voltage to use in the comparator ciruict. After hours of google searches, I've found nothing, and am getting desperate!! I've seen a few previous posts trying to do the samething, but the links he was given are a little complicated for what i'm looking for.
Any help would be greatly appreciated, thanks :roll:
