Simple rotary encoder and button's for controlling Jivelite

I'm making a look a like transporter of an old philips 900 series tapedeck.

To controll Jivelite on a 3.5" screen i ordred ATmega32U4 5 V/16 MHz Module and programmed it according to this website: Buttonbox

You can assign the rotary encoders to up and down, volume up / down, what ever you want. The raspberry will see it as an extra keyboard

Just sharing, maybe you can use it in a next project
