ARDUINO CODE TO PRINT ASCII NUMBER FOR CHARACTERS

Program for printing ASCII number for the character ‘A’, ‘b’ and ‘#’ which are stored in character type variables s1, s2 and s3 respectively.

#include<LiquidCrystal.h>
LiquidCrystal lcd(2, 3, 4, 5, 6, 7);
char s1 = 'A', s2 = 'b', s3 = '#';
int a, b, c;

void setup() {
  lcd.begin(16, 2);
  lcd.print("Hello");
  delay(1000);
  lcd.clear();
}

void loop() {
  a = s1;
  b = s2;
  c = s3;
  lcd.setCursor(0, 0);
  lcd.print(a);
  lcd.print(" "); 
  delay(1000);
  lcd.clear();
  
  lcd.setCursor(0, 0);
  lcd.print(b);
  lcd.print(" ");
  delay(1000);
  lcd.clear();

  lcd.setCursor(0, 0);
  lcd.print(c);
  lcd.print(" ");
  delay(1000);
  lcd.clear();

  // to not repeat the loop again and again
  while (1);
}

OUTPUT

Print ASCII number for characters on LCD 16x2 using Arduino
Print ASCII number for characters “A, b, #” on LCD
