Liquid Crystal Displays
Now we are going to move onto another popular method of displaying text and symbols and that is the LCD (liquid crystal display). These are the type of displays typically used in calculators or alarm clocks. Many Arduino projects use these, so it is essential that you know how to use them, too. LCD displays require driver chips to control them and these are built into the display. The most popular type of driver chip is the Hitachi HD44780 (or compatible); these are used to drive most of the common LCDS.
Creating projects based around LCD displays is easy, thanks to a whole array of LCD code libraries that are ...
