Helloeveryone,
Thisismyfirstpostheresopleasebearwithme.
I'mdesigningmygraduationprojectusinglabview. Partofthisprojectinvolvesacoupleofmotionsensors, whichtriggerabuzzer, led, etc.
Iwouldliketoprogramtheoutputssothattheyaredisactivatedifapasswordhasbeeninserted (e.g. outputsaretrigerredonlyifthesensoristriggeredANDapasswordwasnotinserted...ormaybeinsertingapassworddeactivatesthesensorsalltogether).
Ihaveselftaughtmywaythroughoutthisprojectthroughthegettingstartedguideandalotofsearchingaroundtheforums. MostofmyworkiswithexpressVI,however. I'veattachedasimpleprograminwhichinsertingacorrectpasswordwillenableabooleanusinga "MatchTrue/FalseString", butIstillhaventfulfilledsomerequirements.
1) Afterthecorrectpasswordisentered, thebooleanshouldremainon, stayingsountilitisdisabledbyenteringthecorrectpasswordanothertime. Thisshouldsimulateactivating/deactivatingthesecuritysystem
2) Thereshouldbeanindicationifanincorrectpasswordhasbeeninserted. Notsurehowtodoit.
3)Afterinsertingacorrectorincorrectpassword, theinputstringshouldautomaticallyreturntoitsdefaultvalue. I'vesetthisvaluetoanemptystring
Ibelievethatanyproblemswiththissoftwareareusuallyeasilyresolvable, sohopingthisoneisthesame. ItmightbethatI'minexperienvedwithregularVIs. IveattachedboththemainVIfileandthetestVIthatcontainsthepasswordprompt
