How many button inputs are possible?

I’m trying to make an interface for max/msp, and I’m not sure if arduino is the right chip to get. I want to have a lot of buttons on it, as it would be a sort of keyboard instrument, and it would be nice to have velocity tracked as well. How many inputs like this can the board handle? Thanks a lot.-- Randy

You could do something like this to add multiple switches to a single input.

Hi

How many inputs like this can the board handle?

The basic setup gives you 12 digital inputs and 6 analog inputs.

If you can live wihtout the serial port you can have two more digital inputs. The Arduino BT also has two extra analog inputs.

All kinds of fun multiplexing/scanning schemes are possible using these inputs.. so really you could sense a hundred swtiches if you really wanted to.
