Midi program Arduino nano

Other Hardware Audio
1

Hi. I need help! I have a midi accordion but I have no control panel for program change. It has a 5 pin midi out connected to the sound mode. Does anyone have a wiring and a code to make a simple midi program change with 2 buttons and Arduino nano ( maybe octave control +/-
) Midi in and out to be 5 pins. I do not use usb. Thank you

It is not difficult to do, but it will of course be a modification of your existing code, and we will need to see it for that. Or is it going to be a separate unit ?
The wiring of the buttons can be as easy as connecting a momentary switch with one side to the GPIO pin and the other side to GND and defining the pin as 'INPUT_PULLUP'
Pressing the pin will then result in the result of digitalRead() being 'LOW'

I want to mount it inside the accordion.I don't have a code, I don't have a wiring diagram ... nothing. I'm a beginner :frowning:

So you want it in between the midi-out of the Accordeon and the midi-in of the sound module ?
Just paint us the picture, or show us a picture. What does the inside of the accordeon look like ?How is it powered ? Could we maybe take the signal from before it is send thru the midi output ?

Unfortunately i am not psychic enough to answer those questions. And being a beginner doesn't mean you are helpless. You can research how to receive and send midi signals with an Arduino. You can research midi i general. You can try if you can make the internal LED of an arduino turn on and off using momentary switches. There are many things you can do. If you want someone else to do it all for you, then i suggest you try the Gigs and Collabs section, but don't forget your wallet.

I want to use this project connected to the midi out on the accordion to Arduino midi in and midi out Arduino to the sound module Thanks for the time given. I will study this issue intensely, and I will return to this project

I also used Arduino..I built self winding watch box, midi bluetooth with esp32 :slight_smile: Thanks anyway
