What it does
We would like to create a program that detects whether or not a note played on an instrument matches a predetermined pitch. This tool will be useful for musicians who wish to tune their instruments, as it is programmable to any note. For example, if a note is played, the computer will print whether or not the pitch is the same as the intended pitch and, if not, whether the pitch needs to be higher or lower. The project requires connecting a microphone to the Arduino, and then processing the signals picked up and matching them to the given frequency for a note. Several frequencies can be programmed to represent any note.
