Text are printing very well.. but some of characters like symbols,arrows,drawings are not display.. i tried many times.. Not done.. HELP ME.

i tried one of sample code:


  Special char test for i2C LCD



#include <Wire.h> 

#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 16, 2);  //sometimes the adress is not 0x3f. Change to 0x27 if it dosn't work.

uint8_t arrow[8] = {0x00, 0x04 ,0x06, 0x1f, 0x06, 0x04, 0x00}; //Send 0,4,6,1F,6,4,0 for the arrow

void setup() {




  lcd.createChar(0, arrow); //We create the data to be sent later using lcd.write


void loop() { 

  lcd.home();           //Home the cursor

  lcd.clear();          //Clear the LCD

  lcd.setCursor(0,0);   //Stat at the first row first column

  lcd.write(0);         //Sent the character that we've made          //delay between each loop

}//end of void


This code tried in ARDUINO NANO...sadsad

Hi. I think you don't have the lcd.init(); function in the setup loop. Add that line and dry again!
