# Seven segment display in labview : tutorial 25

In this tutorial I will help you to design a VI that will display the number of your demand on a seven segment LED display. You will provide a constant value as input and at VI will display your entered constant on a seven segment display. Using all the knowledge you have gained so far, you will be designing a simple VI as a sample project in this tutorial. At the end of the tutorial you are provided with an exercise to do it by yourself, and in the next tutorials I will assume that you have done those exercises and I will not explain the concept regarding them.
