    Hi guys

    I am looking for a cool buzzer sound combination. My project have a CLI, I thought I may add a secret command to it and play something cool/funny. Any idea?

    My buzzer only can be on off, can't change the tone.

    There are tone chips available, maybe Spark Fun ? Also you can roll your own with a SN76477N Complex sound generator, 28 pins of fun.

    Beep out your initials in Morse Code. I did this for an airport RADAR controller. One of the indicator lights blinks periodically, and to the eye it looks like a normal LED blink. Actually, every time it blinks it is flashing my initials very rapidly. I borrowed the idea from the BORG.

    Is CLI a command line interface? Are you asking how to use existing sound hardware with the CLI?

    I haven't seen one of those in a long time.

    I think my option is limited to software only.
    Haha I like this idea :)

    I am writing the firmware, part of the function is command line interrupter. The firmware is finished. I just want to add an extra secret command to do something cool/fun. :)

    How about a "ding - dong" door bell. Single chip, M602. Lots of data sheets on google but I can't find a state-side source for this one.

    Even a single chip cannot be added with software.
