Just wanted to know if my flow chart for the program i posted is correct. (attached)

Hi kasamaneka,

using a proprietary file format for some pictures isn't very helpful here (my OpenOffice doesn't like your MSWord artwork)...

Please attach pictures (PNG format preferred)!

You did not give a reply to my previous email requesting for the Vi, you created or modified. Anyways attached is the flow chart in picture format. Id be greatful if would suggest for some improvements.

Greetings Kasamaneka.

I noticed in your flow chart that there is no loop, unless the voltage is under 2.5 Vrms. According to your diagram, the light conditions are only checked once, and then the program ends. Is that the behavior that you intended? Also, according to your diagram, there is no way to differentiate between the Vrms value being less than 2.5; 2 or 1.5 (Did you meant Vrms > 2.5 ; 1.5 < Vrms < 2.5 ; Vrms < 1.5 ?) 

Since you are a beginner, I recommend that you read some of NI's documents on where and how to start with data acquisition and LabVIEW.

Hi kasamaneka,

I cleaned up the VI to use arrays for all those comparisons and calculations. I also enabled numeric display for your fancy gauges eliminating additional indicators.

I guess it looks better now (in the block diagram)...

I wanted to see the vi but does not open in my version 8.5.
