This demonstrates a 2 wire( two wire) LCD serial interface. With a cheap 74LS174 Hex Flip Flop acting as a shift register. An LCD can be driven with only two cables the Data and the Clock. This will free up a lot of pins in your project . Great for debugging and smaller MCU's to save precious I/O's.
