    Hello, guys.
    I changed arduino uno board to newer version.
    (So it is DIY :) )
    It works nicely but, motors
    make high pitched noise on
    Fpwm value 5khz and 10khz
    (5khz noise is relatively lower)

    But i cannot hear it with setting 15khz and above.

    Is it normal? Is there anybody who is experiencing this ?.

    Kindly give me advice.
    Thanks.
