So I thought something like this might exist but I don't see one anywhere, hoping I don't have to roll my own.
What I would like is a keyboard that when I press A sends A to the serial port on the arduino. No screen needed or anything. I just want to send keystrokes to the arduino as though it was coming from a serial program.
Bonus points for it being small.
Anyone know of anything like this? My googling didn't return much other than ps/2 keyboards.
