The circuit:
- LCD RS pin to digital pin 12
- LCD Enable pin to digital pin 11
- LCD D4 pin to digital pin 5
- LCD D5 pin to digital pin 4
- LCD D6 pin to digital pin 3
- LCD D7 pin to digital pin 2
Parallel LCDs run off of +5V so you can just solder the Vcc (pin 2 in LCD)wire to 5V and the ground (pin 1 in LCD) wire to GND.
