so i recently wired up my own keyboard via a matrix controlled by an arduino micro and i wrote my own keyboard driver, so this keyboard is now totally functional and all, but it requires a wired connection to the computer via usb
what i would really appreciate help on is a cheap way to create a wireless keyboard similar to commercially available wireless keyboards, something like a logitech wireless dongle would be very nice
currently the only ways i figured out how to archive my goal are the following
- using a bluetooth serial module wired to the arduino
- using a rf link connector pair such as these http://www.seeedstudio.com/depot/433Mhz-RF-link-kit-p-127.html
are there any better/cheaper solutions out there?
