Function changeColor will send the keystroke 'CTRL+K' to the computer The compiler error is being generated because you are calling the Serial.write() function incorrectly.
#SENDING KEYSTROKES TO ELINKS CODE#
Modern keyboards use a scan code for the modifier keys and I have no idea whether the ASCII values will work for your application. The control key is a modifier which, in ASCII, clears the 2 most significant bits of the 7 bit character code, the modifier key is applied to. I am having troubles finding the correct HEX, ASCII, or Decimal for this.
#SENDING KEYSTROKES TO ELINKS SERIAL#
I am trying to send ctrl+k keystroke through serial write to my computer.

I don't understand the error and warning yet. I have spent two days looking for the key command without sending to a scanner or LCD display. I would appreciate any help with either the proper search topic or help with code. I am using an additional program ACC Keys to capture the serial data. I have successfully sent the space command. I understand that this is not a Leonardo or a FLASH DFU Arduino. I get a compiler error when working my way.
