lcd 400 display arduino wiring code example

Example: arduino lcd hello world

// include the library code:
#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {
  // set up the LCD's number of columns and rows:
  lcd.begin(16, 2);
  
  // Print a message to the LCD.
  lcd.print("ROBO-CREATORS");//YOU CAN CHANGE IT
}

void loop() {
  // set the cursor to column 0, line 1
  // (note: line 1 is the second row, since counting begins with 0):
  lcd.setCursor(0, 1);
  
  // print the number of seconds since reset:
  lcd.print(millis() / 1000);
}
