In the fourth Arduino Tutorial we explore the world of Liquid Crystal Displays which are more commonly known are LCDs. These displays allow you to display a certain number of characters directly from your Arduino; they are extremely useful if you want to do any remote sensor monitoring or data retrieval.
Arduino provides a great library for basic displays which use the HD44780 Protocol. It makes it extremely easy to have your display working for your projects.
