2. After clicking Create Project, you will enter another interface, select the project type you see, and select VI, because labview is composed of VI. Click Create Blank VI, and then click Finish.
3. At this time, two panels will pop up, one is the front panel and the other is the program block diagram. The front panel is the view diagram, where the tool plug-ins are stored, and the program block diagram is the block diagram connecting these tools, which is the interface for writing.
4. You can put some controls on the front panel and then connect them with the program block diagram, as shown in the figure. Write a small-volume program and select a control on the front panel. Select the liquid tank in the numerical value, and it will also be displayed in the program block diagram.
5. Edit the numerical size of the liquid tank and change the label to volume, as shown in the figure below.
6. Then right-click on the program block diagram to add a random number, add a multiplication function, fill in the numerical value 1000, and connect with the volume.
7. Now, click Run above, and it will run once. Randomly give a value from 0 to 1 and multiply it by 1000, which is the volume of this volume, thus constructing a simple running program.
