Bluetooth Speaker Amp - Replacing Analog Pot wth Digital Pot

[stuartpurdue]

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.
