Hello, i cant make it to work.
i have this LCD
And i cant make it work with this program
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x20, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); // Set the LCD I2C address
void setup() {
Serial.begin(9600); // Used to type in characters
lcd.begin(20,4); // initialize the lcd for 20 chars 4 lines and turn on backlight
lcd.setCursor(3,0); //Start at character 4 on line 0
lcd.print("Hello, world!");
delay(1000);
}
void loop() {
}
When i get the program in the Arduino i only get the first and third line in black squares.
This is only the beginning of the project and im stuck! jajajjajaja
Help me if you know how.
Thank you.
