Hi everyone !
I'm novice in Arduino code ... And I need your help for a project.
My problem is this one : I have to design a system to record a melody with 10 notes. The system takes a rectangular signal as input, records it and outputs a melody close to the original signal. I need to add a button to start recording the 10 notes of 1 second each, and another button to start playback (PWM signals generated by the Arduino).
I don't understand how to make this in code with Arduino.
Thank you !
