Buenas tardes, soy nuevo en el foro y quería saber si me podrían ayudar, estoy trabajando con el modulo lcd NOKIA 5110, y no logra hacer que me imprima un string en la pantalla (no asi en el monitor de arduino); me podrían guiar.. muchas gracias.

Hellow guys I'm new in the forum of arduino; and i have an issue, i'm working whith de lcd module of NOKIA 5110, and i can't make the lcd module to print an array. could you help me??(sorry for my English)

Thanks

#include <Nokia_LCD.h>


Nokia_LCD lcd(3 /* CLK */, 4 /* DIN */, 5 /* DC */, 7 /* CE */, 6 /* RST */);

String ArrayNombre[3]{"FUEGO","CIELO","TIERRA"};
int i = 0;


void setup() {
  lcd.clear();
  lcd.begin();
  lcd.setContrast(50);
  delay(500);
  Serial.begin(9600);
  
  }

void loop() {
  lcd.clear();
  lcd.begin();
  lcd.setContrast(50);
  randomSeed(millis());
  i=random(0,3);
  Serial.println(i);
  Serial.println(ArrayNombre[i]);
  lcd.begin();
  lcd.setCursor(15, 2);
  lcd.println(ArrayNombre[i]);
  delay (1000);
 }

You don't need all those lcd.begin() statements in your code. One inside setup() is enough.

The println() function wants a const char * not a String.

Luckily, the String class has a function that returns the underlying string (lowercase 's')

   lcd.println(ArrayNombre[i].c_str());

Thanks Very much..!!!
