Introduction:
toneMelody() function use PWM to generate different frequencies that could generate different sound. The tone function is shown like below:-
For tone, the first number is the output pin, second – frequency, and third – node duration. We can use the sample code from Arduino IDE. We just go to:-
File>Example>Digital>toneMelody
Then we get the sample code as follows:-
We need to make sure that, the connection of speaker pin out at the right pin. In this example, the pin out was set at D8.
Let try. Good luck.
