Hi!
I want to create a sound frequency detector circuit. I want to determine the frequency of a sound and then output an analog voltage so I can use the ADC of my PIC16F877a. I plan on using an electret microphone.
I want to know the frequency/pitch of an object when I tap it so I that can discriminate the different types of objects being tapped.
For example, a glass bottle has a higher pitch than that of a plastic bottle.
Can you give me any suggestions on how to approach this project?
Thank you very much!
