for this i added a trailing zero in case the value is less then 10. Use if-else statement
lcd.print("0"); \\ if value less then 10
lcd.print(""); \\ if value is more then 10
I am a beginner myself so i am sure this is a really crude method and lot of people will suggest more efficient coding but well , we all are learning ..aint we...
