Source Code

#include <EMLcd.h>
EMLcd lcd(4,5,6,7,8,9);
char line1[16];

uint16_t c=0;

void setup() {
  lcd.init();
  lcd.clear();
  lcd.print_xy(0,0,"Embedded Makers");
  lcd.print_xy(0,1,"LCD16x2 Demo");
  delay(1000);
  lcd.clear();
}

void loop() {

  sprintf(line1,"Counter : %d",c++);
  lcd.print_xy(0,0,"Variables");
  lcd.print_xy(0,1,line1);
  delay(1000);
  lcd.clear();
