Generally for connecting an LCD display to an Arduino using 7 strands,
it usually breaks the leg that has any projects that remain few ports to
be used. But there is a way, using an IC 74LS164 (8-bit serial shift
register), a resistor and a diode, but it's not just hardware, you have
to use a library.
This Arduino library for connection of 2-wire or 3-wire using HD44780
compatible LCD display via shiftregisters. This circuit is considered
"deprecated", but it's worth testing.
