Shield

Sart again from the beginning. The proof of concept is done, so now I will try to improve oboïno functionalities and make a better conception.

First of all : make a shield.
This will allow me to add/remove every analog or digital input without unsoldering everything.
The shield will give access to all the 6 analog inputs of UNO, and 10 digital inputs (this will be enough). I will put a MIDI OUT (new functionality).
Connections are arduino basics. Digital pins are connected like this :

Analog like this :

And MIDI like this :

Each analog inputs come with 3 pins connectors.
All digital inputs are connected with a 16 pin connector. I use 11 pins :
1 pin to bring 5V to each switch
10 pins to connect switches to arduino digital inputs.
