#Arduino lcd library shift text download
To simplify communication between Arduino IDE and LCD module, we need to download LiquidCrystal library to make use of a built program in Arduino. PIN6 or E (Enable) to PIN 11 of ARDUINO UNO.PIN4 or RS (Register Selection) to PIN 12 of ARDUINO UNO.

PIN3 or V0 to potentiometer and other leads of potentiometer connected to arduino.PIN1 or VSS and PIN5 or RW (Read/Write) are commonly to ground.The connections which are done for LCD are given below: Pin 16 (CATHODE/LEDK/-ve pin of the LED): This pin is connected to GND. Pin15 (ANODE/LEDA/+ve pin of the LED): This pin is connected to +5V In 4-wire mode, only four pins are connected to the microcontroller unit like 0 to 3, whereas in 8-wire mode, 8-pins are connected to microcontroller unit like 0 to 7. These pins are connected in two-wire modes like 4-wire mode and 8-wire mode. Pins 7-14 (Data Pins/D0……D7): These pins are used to send data to the display. Pin 6 (Enable(E)): This pin should be held high to execute Read/Write process, and it is connected to the microcontroller unit & constantly held high. Pin5 (Read/Write(RW)): This pin toggles the display among the read or writes operation, and it is connected to a microcontroller unit pin to get either 0 or 1 (0 = Write Operation, and 1 = Read Operation). Pin4 (RS/Register Select/Control Pin): This pin toggles among command or data register, used to connect a microcontroller unit pin and obtains either 0 or 1(0 = data mode, and 1 = command mode). Pin3 (V0/VEE/Control Pin): This pin regulates the difference of the display, used to connect a changeable POT that can supply 0 to 5V. Pin2 (VCC/VDD/Source Pin): This is the voltage supply pin of the display, used to connect the supply pin of the power source. Pin1 (VSS/Ground): This is a GND pin of display, used to connect the GND terminal of the microcontroller unit or power source. LCD 16×2 Pin Diagram The 16×2 LCD pinout is shown below. Now in the 14 pins there are 8 data pins (7-14 or D0-D7), 2 power supply pins (1&2 or VSS&VDD or GND&+5v), 3rd pin for contrast control (VEE-controls how thick the characters should be shown), and 3 control pins (RS&RW&E). One can power or leave the back light pins. In 16×2 LCD there are 16 pins over all if there is a back light, if there is no back light there will be 14 pins. Working with both 8-bit and 4-bit mode.Each character is built by a 5×8-pixel dots.Consists of two rows and each row print 16 characters.Alphanumeric LCD display (alphabets, number, special characters).So, it will have 16×2 = 32 characters in total and each character will be made of 5×8 Pixel Dots. There are a lot of combinations available like 8×1, 8×2, 10×2, 16×1, etc. 16×2 LCD is named so because it has 16 Columns and 2 Rows. This tutorial we build two projects with arduino board firstly interface with simple LCD module and secondly interface with LCD I2C Module respectively. In normal development boards interfacing LCD to a ARDUINO is quite easy with circuit and code.

Now, we are learning how to Interface LCD to Arduino and display text characters on LCD screen. LCD’s are generally used as a display in many applications as they are easy to use then seven segment displays. To developing a good communication between machines and human beings, display units play an important role of embedded systems.
