Write from Arduino to LCD

 Scheme Description:

• Connect the LCD RS pin to the Arduino pin 12
• Connect the LCD enable pin to the Arduino pin 11 
• Connect the LCD D4 to D7 pins into pin 5 to 2 Arduino
• Connect the LCD +5 and ground to pin +5 V and ground Arduino
• Connect the pin to a potentiometer LCD Vo. Use of this potentiometer is to adjust the LCD contrast

In this Project, we will write " Hello World " from arduino to LCD

Program Arduino:

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23

// LCD Demo Program // Use LCD library #include "LiquidCrystal.h"; // LCD initialization & use pin LiquidCrystal lcd(12, 11, 5, 4, 3, 2); void setup() {   // Set the numbers of LCD columns and rows   lcd.begin(16, 2);   // Make the writing on the LCD   lcd.print("hello, world!"); } void loop() {   // Set cursor to Column 0 & Row 1   // Note: Column & Row starting with 0   lcd.setCursor(0, 1);   // Print the number of seconds since last reset   lcd.print(millis()/1000); }
