Connect power amplifier

Hello!,

I need some help.

I'm doing a project in arduino and I need to connect a power amplifier with speakers connected (link) to arduino so I can control the volume from there.

I have bought two FSR sensors (force) and I want to control the volume from the amplifier depending force applied to this sensor.

I've used ableton live to generate the 60hz signal I need for this but Ive tried by moving the knobs manually.

My questions, How can I do to control that volume from my arduino? Anyone here have done something similar or give me some tips in order to make it work?

Thank you very much for your help!!

My first thought is to anntenuate the incoming signal, for example using a potentiometer to adjust the volume.

You could use a digital potentiometer and control the chip which adjusts volume level based on pressure sensor data.

But there's probably an easier way ...

You can use servo to control the volume control pot.
