Hi guys,
I’m a newbie, so apologies if I’m doing it all wrong. I’ve got my music shield several days ago and since then trying to figure what digital pins it uses and what’s left. I need to wire 6 buttons in my project which means I need at least 5 digital in’s. I was looking through the docs with board design pictures and at the board itself, but can’t figure what’s unused. There are some pins (1 and 10-13) that look vacant, but still labeled (10-13).
If it uses all of digital pins, is there a way I could share them somehow? Also, since I don’t need control buttons (volume, rew, play etc), could I hook on to them somehow?
Cheers,
Hi,
You can use D3-D9 if you don’t want to use the on board button, switch, and LEDs.

Hi Steve,
Thanks for the suggestion. Any way you could recommend doing this without soldering? If there isn’t that’s ok, I just wanted to minimize the changes to the board and the shield.
Cheers,
Well, it seems a little bit difficult to solder if you are using Arduino.
But it becomes much easier if you are using Seeeduino as it has another parallel pins.

Yup, I’m a happy owner of Seeeduino v2.21. I was thinking of grabbing a larger protoboard at a local store, soldering the connectors onto it and between the main board and the shield. I would then solder another connector on the side for easier pins access. Yes, some extra height, but no modification to either main board or music shield. Looks like a nice and clean solution. We’ll see.
Thanks for the answers!
