LCD DISPLAY

 


What is the LCD display?
LCD (Liquid Crystal Display) is a type of flat panel display which uses liquid crystals in its primary form of operation. LEDs have a large and varying set of use cases for consumers and businesses, as they can be commonly found in smartphones, televisions, computer monitors and instrument panels.
Liquid crystal displays (LCDs) are used with Arduino because they are a good choice for Arduino projects and can provide a user interface: 
 
  • Easy to use: There are libraries that make it easy to control LCD functions, including wiring and coding. 
     
  • Low power consumption: LCDs use very little current. 
     
  • Commonly used: LCDs are used in many electronic devices, such as calculators and microwave ovens. 
     
Here are some things to know about using LCDs with Arduino: 
 
  • LiquidCrystal Library
    This library allows an Arduino to control LCDs based on the Hitachi HD44780 chipset, which is found on most text-based LCDs. 
     
  • 4-bit or 8-bit mode
    The LiquidCrystal Library works in either 4-bit or 8-bit mode. 4-bit mode requires seven I/O pins from the Arduino, while 8-bit mode requires 11 pins. 
     
  • Display contrast
    The display contrast pin (Vo) can be used to control the display contrast. 
     
  • LED backlight
    The LED Backlight (Bklt+ and BKlt-) pins can be used to turn on and off the LED backlight. 

  •  

  • You can easily interface a liquid crystal display (LCD) with an Arduino to provide a user interface. Liquid crystal displays (LCDs) are a commonly used to display data in devices such as calculators, microwave ovens, and many other electronic devices..
