How to use LCD with Arduino Uno

Liquid crystal Display 16×2 (LCD) is a widely used electronic device to establish communication between the real world and the electronics-based machine world.

There are multiple devices available in the market such as seven-segment displays, graphics displays, multi-segment LEDs, and so on but LCD is the most preferred display device because of its amazing features. Liquid crystal display’s unique features are as follows:

• Consists of two rows, with the capability to display 16 characters in each row.
• Cable to display alphanumeric characters (means it can display numbers and alphabets).
• Low power consumption.
• Works on the principle of blocking light instead of emitting light.
• Require less operating voltage.
• Each character is built by a 5×8 pixel matrix.

In this tutorial, we will deal with a 16×2 Liquid crystal display compatible with the Hitachi Hd44780 driver.

I will explain to you two simple projects to understand all the basics of LCD. The first project will help you to understand how different commands are used in Arduino and how their result shows on the LCD screen.
