How To Print Big Size Numbers on 16x2 Lcd.

You need to connect the lcd ( 1602 or 16x2) in the following way: Beginners tutorial to lcd  : https://www.arduino.cc/en/Tutorial/HelloWorld The code :
 #include
   int input = A0;
 LiquidCrystal lcd(12,11,5,4,3,2);
 BigNumbers bigNum(&lcd); // construct BigNumbers object, passing to it the name of our LCD object
 void setup() { TCCR1B = TCCR1B & 0b11111000 | 0x01; // use for Arduino Uno // TCCR2B = TCCR1B & 0b11111000 | 0x01; // use for Arduino Mega2560 pinMode(input,INPUT); lcd.begin(16,2); // setup LCD rows and columns bigNum.begin(); // set up BigNumbers lcd.clear(); // clear display } void loop() { int value=analogRead(input); bigNum.displayLargeInt(value, 0, 5, false); // value is integer,5 is print position // 1 to 6 for position lcd.setCursor(0,0); lcd.print("Value"); delay(200); } End.
