So today I will tell you how to use the 16x2 LCD display on the Arduino projects. If you are doing any kind of projects then you should interact with the user in the simplest process.To add any kind of output device is the key to simplify that project. you may show the options or the compilation details using that. There various types of displays available in the market but among them the 16x2 LCD display is the famous and cheapest one.As it has a very simple process to implement them in the projects. pinout for the 16x2 LCD display: circuit diagram for 16x2 LCD display: Test code to check the connection is properly done or not: /* LiquidCrystal Library - Test code #DNY Demonstrates the use a 16x2 LCD display. The LiquidCrystal library works with all LCD displays that are compatible with the Hitachi HD44780 driver. There are many of them out there, and you can usually tell them by the 16-pin interface. The circuit: * LCD RS pin to
