Forgive me for not being knowledgeable enough on this subject yet as I've just taken it up recently but for our prototype project, I've chosen to do a four-string banjo tuner. What I plan to do is similar to that of a guitar tuner with LED's lighting up to indicate whether the string is flat, sharp, or in tune and I know that this will be pretty simple to make once I learn to fully understand the concept.
But please note that I'm still learning the different types of logic circuits so I was wondering if any of you could give me a guide on how I will start building the circuit in a breadboard. I'm still not familiar on the types of components I need for the circuit to detect the frequency of the string until it matches to the correct one and how a logic gate will come into play when indicating which LED should light up. We need to apply either sequential logic, counters, or registers but we haven't studied all of them yet so any kind of information about this will really be helpful.
