    Hello All,

    I've recently been working on a project of designing a portable Bluetooth speaker. I'll be using a cheap 'Yamaha' amplifier that I bought from China, this amplifier features a potentiometer that controls the volume.

    I'd like to replace this with some volume buttons. I have little-to-no knowledge on how to do this.

    I believe I need to replace the analog pot for a digital pot, but how I control this I have no idea - I'm hoping I will get chance to use an arduino I bought a few years back...

    I'll update this thread with more info and pictures when I get home from work.

    Any help will be greatly appreciated

    Regards

    Stuart

    The datasheet for a digital pot shows how to use it.
