title: Is it possible to use a keyboard as an input in Arduino Uno?
body: <p>I'm new to Arduino, this may be a dumb question but can I use a keyboard to be the main input like a series of buttons but only using a USB/PS2 connection, which will use fewer input pins? I know Arduino Leonardo can emulate a keyboard, but can I use a keyboard as an input to the Arduino? Is it possible? I need a lot of inputs and I'm using an LCD too.</p>
