• It is a Graphical-based programming language
• LabVIEW Programs are Called Virtual Instruments
• LabVIEW relies on graphical symbols rather than textual
language to describe programming actions
Introduction
4. Comparison
Text Based Programming Graphical Programming
• It is Text based Programming • It is icon-based programming and
wiring
• Text based programming is not
interactive
• Graphical programming is highly
interactive
• Syntax must be known • Syntax is not required
• Front panel design needs extra
coding or needs extra work
• Front panel design is a part of
programming

Water Level Controller using PID Controller
• The idea of the
project is to keep
the level of water at
the desired set
point.

Temperature Sensing
• The project aims on virtually sense the temperature
of the system and tell that the system is at high
temperature, medium temperature or low
temperature.
