menampilkan data ke LCD 16x2 menggunakan ESP32

bahan:
- ESP32
- LCD16x32
- Potensiometer 50K
- jumper

mapping pin:

sketch :

#include <liquidcrystal.h>
LiquidCrystal lcd(22,23,5,18,19,21);

void setup()
{
    lcd.begin(16, 2);
    lcd.clear();
    lcd.print("Hello fixduino!");

    // go to row 1 column 0, note that this is indexed at 0
    lcd.setCursor(0,1); 
    lcd.print ("LCD pakai ESP32");
}

void loop(){}

Menggunakan Modul I2C
sketch:

#include <wire.h>
#include <liquidcrystal_i2c.h>
LiquidCrystal_I2C lcd(0x27, 2, 16); 

void setup()
{
    lcd.begin();
    lcd.clear();
    lcd.print("Hello fixduino!");

    // go to row 1 column 0, note that this is indexed at 0
    lcd.setCursor(0,1); 
    lcd.print ("LCD I2C by ESP32");
}

void loop(){}
