How to Set Up and Program an LCD Display on an Arduino via Circuit Basics
Every computer (or microcontroller, which is truly what the Arduino is) needs a display. What good is gathering sensor data if you can see it, right? Enter the 16x2 line LCD that uses the Hitachi HD44780 driver chip/. These boards are available in many places, including eBay and Amazon, and libraries exist to let your Arduino talk to them in just a few minutes of coding. You’ll see them used in many Arduino and Raspberry Pi projects, so learning how to use them is a skill you can use over and over in your projects.
This is s a very detailed walk-through of using these LCD displays including connection diagrams and code explain nearly all the functions of the LCD Display library.
