Adding a LCD to any project immediately kicks it up a notch. This tutorial explains how to connect a inexpensive HDD44780 compatible LCD to the raspberry pi using 6 GPIOs. While there are other ways to connect using I2C or the UART this is the most direct method that get right down to the bare metal.

This technique:
  • allows for inexpensive LCDs to be used
  • does not require any i2c drivers
  • won't steal the only serial port on the Pi.

The example python code sends date, time and the ip address to the display. If you are running a Pi in headless mode being able to determine the IP address at a glance is really handy.
