I built a board to hold an LCD and the parts to control it. I started it over a week ago, and finished it today(I forgot about it). it uses the shiftreglcd library and a 74ls164. To save one I/O pin, the design included an AND gate made from a diode and resistor. The board reduces a complicated LCD to data, clock, power, and ground. This will keep me from having to make a whole circuit when I want an LCD in my Arduino projects.
