title: creating NI labview alarm
body: <p>I'm trying to build an application thats asks a patient in the hospital how he or she is feeling, if the patient responds "well" I want to create an alarm that after two hours repeats the same the question, or if that's not possible to turn on a led or an alarm which will alert the patient to register his or her health status (well/unwell).</p>
  
  <p>So far i've used a case structure and a while loop but i'm confused on how to create the alarm/get it to work. </p>
