Please don't simply post something you haven't even looked at. Look at where the error is and see if anything jumps out at you. If not, go learn how to program. This is a simple error.

Make sure the "print" function supports the data types you have specified, and check your syntax that writes content to the Liquid Crystal Library.

hi
dear all thanks for your support these code's are working in ARDUINO for my project
thanks once again
