Possible to make a keyboard using an arduino and nothing else?

Hi all,

a friend and I have been thinking about trying to make our custom keyboard, without a keyboard controller, just an arduino, buttons and wires.

Is this possible? The arduino would be one of the arduino's that supports the Keyboard library (here), and I think that could work.

Thanks.

Yes. Matrix keypads are nothing but "buttons and wires".

Sure it is, you do not even need a USB capable Arduino: e.g. PPM2USB - R/C PPM to USB-Joystick Adapter - PPM2Joiystick - there are usb keyboards from the same time around. Or you might simply go for a leonardo or anything with atmega32u4 or samd.
