ARDUINO Code:

// CUSTOM TEXT:

#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); // Set the LCD I2C address

void setup()
{
lcd.begin(16, 2); // initialize the lcd for 16 chars 2 lines, turn on backlight
lcd.clear();

}
void loop()
{
lcd.setCursor(5, 0);
lcd.print(“BASIC”);
lcd.setCursor(4, 1);
lcd.print(“ARDUINO”);
delay(2000);
lcd.clear();
delay(2000);

}

 

//LCD Potentiometer:

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);
void setup()
{
lcd.begin(16, 2); // initialize the lcd
lcd.clear();

}
void loop()
{
int val = (analogRead(A1)); //read analog pin A0
lcd.setCursor(5, 0);
lcd.print(“VALUE=”);
lcd.setCursor(6, 1);
lcd.print(val);
delay(500);
lcd.clear();
