Need help to connect 8 rotary encoders and 8 switches to arduino as midi control

Hi

Can anyone help or guide me as i want to make a midi controller to control Lightroom and ease out my workflow.

My aim is to connect 8 rotary encoders and 8 switches (apart from the inbuilt switches in rotarty encoders) to an arduino Uno or an arduino pro micro so tht i can use it as a USB midi controller and then map the controller to a midi mapping software.

I know a bit about electronics, soldering and uploading code.
But i have no idea of coding or anything of that sort.

I would really like someone to help me with the connections and also the code.

It would be of great help.

Thanks!

No.
I can’t see how you can use an I2C multiplexer in any way to do that.

What is Lightroom?

Why rotary encoders? They don’t keep their position through power cycles and if it is a MIDI control you will have to restrict the numbers in software to make it look like you have a pot anyway. This is a lot simpler to do with pots.

With a rotary encoder you need at least one but preferably two interrupt capable pins to read them, which would involve using the pin change interrupt feature of the processor.
