Expansion IO (by jimson james)
YES you can use two microcontroller, one is for input and another is for output...using microcontroller i recommend to use atmega128 for wider memory capacity. connecting them using uart... input will transmit the ascii code to receive by the output microcontroller.... and the the output will transmit back the logic to acknowledge the data has been transmitted...
