SDR VFO Midi Controller - Hamradio - Amateurfunk

I needed a midi controller for the Square SDR. Found one here, but the sketch did not work for me and i also did not like the huge housing it had.

So, i read, and did put together a working sketch for an arduino micro pro.
It has:
2 encoder
1 poti
4 simple push buttons.

I did not activate the push buttons on the encoders as i preferred the 4 buttons.

The housing is rather small but the arduino micro pro is small so everything did fit in tightly.

The bottom is supposed to be screwed on, but most screws won't fit. I recommend you fill the holes with some hot glue and just take some screws which would fit then (or you just edit it :) ).

Used also this https://www.amazon.de/dp/B0754MNQPN?psc=1&ref=ppx_yo2ov_dt_b_product_details as i wanted to place the arduino anywhere in the box and get enough space for the buttons.
