Hi, just started a project and want to build usb keyboard, that has the following input; numbers 1,2,3,4,5, left arrow key and right arrow key (ideally using arcade sanwa buttons). I’ve looked at the arduino pro micro board but still unsure what to use. Was just wondering what is the best way of approaching this, the hardware I need to buy, or any useful tutorials that would be helpful. Thanks
