keyboard circuit diagram

This is more or less the current circuit layout:

From keyboard

Current problems: LCD stays lit and powered while the PC is turned off, possibly due to wake on keyboard/mouse being enabled..

I'm planning to add:

  • a rotary encoder for navigating menus
  • keeping track of stats like words per minute
  • switching backlight power
  • arduino reset button
  • morse code input?

Long term i'm aiming to have the arduino connected directly to USB, but i'm not sure if it'll cope with the extra load..
