There are a few useful functions you can use with LiquidCrystal object. print( ' LCD Tutorial') Other useful functions in LiquidCrystal Library Connect pins 1 and 16 on the LCD to GND and pins 2 and 15 on the LCD to 5V. The LCD has two separate power connections One (Pin 1 and Pin 2) for the LCD itself and another one (Pin 15 and Pin 16) for the LCD backlight. LetРІР‚в„ўs test your LCD.Р”Р‡irst, connect the 5V and GND pins from the Arduino Uno to the breadboard power rails and get your LCD plugged into the breadboard. For example, if we want to see the uppercase РІР‚ВAРІР‚в„ў character on the display we will set these pins to 0100 0001(according to the ASCII table) to the LCD.Р”Р„-K (Anode & Cathode) pins are used to control the backlight of the LCD. Meaning, when this pin is set to LOW, the LCD does not care what is happening with R/W, RS, and the data bus lines when this pin is set to HIGH, the LCD is processing the incoming data.Р”В0-D7 (Data Bus) are the pins that carries the 8 bit data we send to the display. This forces it into the WRITE mode.Р”В® (Enable) pin is used to enable the display. Since weРІР‚в„ўre just using this LCD as an OUTPUT device, weРІР‚в„ўre going to tie this pin LOW.

R/W (Read/Write) pin on the LCD is to control whether or not youРІР‚в„ўre reading data from the LCD or writing data to the LCD. And when RS pin is set on HIGH we are sending data/characters to the LCD. Basically this pin is used to differentiate commands from the data.Р”Р‡or example, when RS pin is set to LOW, then we are sending commands to the LCD (like set the cursor to a specific location, clear the display, scroll the display to the right and so on). RS (Register Select) pin lets the Arduino tell the LCD whether it is sending commands or the data. Using a simple voltage divider with a potentiometer, we can make fine adjustments to the contrast. Vo (LCD Contrast) controls the contrast and brightness of the LCD. VCC is the power supply for the LCD which we connect the 5 volts pin on the Arduino. GND should be connected to the ground of Arduino.
