What if you could do it with one line of code, inside the comfy confines of Arduino? Interested? Well, say hello to my micro friend: the SparkFun Pro Micro! How cool would it be if you could turn any button, joystick, sensor or other electronic gizmo into a USB keyboard and/or mouse? You could make just about any input device you want into a controller for your computer programs or games. Turn your ProMicro into a USB Keyboard/Mouse
