I have decided to enter the world of microcontrollers. I ordered a couple Atmel AVR series microcontrollers to play with. I wanted to order an LCD display as well, but I wasn't sure what to get.

I am not sure what these really mean, but these are the categories I have to choose from:
  • 4 Bit, 8 Bit Data Bus
  • 4 Bit, 8 Bit, Serial SPI
  • 4 Bit, 8 Bit, SPI 4-wire
  • Parallel
  • Serial


I recognize the last 2, but I am not sure which of those would be the one to get.

The microcontroller that I would want to hook an LCD up to is an Atmega168.
