Adding a LCD to any project immediately kicks it up a notch. This tutorial explains how to connect an inexpensive HDD44780 compatible LCD to the Raspberry Pi using 6 GPIO pins. While there are other ways to connect using I2C or the UART, this is the most direct method that gets right down to the bare metal.
- 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 Pi's 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.
