Hi. I am trying to create an application that consists of 2 timers (count down in seconds). When 1 timer finish, the other timer will start. When the other finish, the 1st timer will start. These will loop for a pre-determined number of cycles. I have tried modifying the timers found at http://sine.ni.com/apps/utf8/niepd_web_display.display_epd4?p_guid=B45EACE3DFD556A4E034080020E74861 but I can't seem to get it to work in terms of seconds. Kindly advise.

ni.com is currently undergoing scheduled maintenance.

Hi Amal,

I have not had a chance to get the LED's working as you would like, but here is what I have so far. Please take a look at the VI's block diagram and see if you can play around with it as well. Since you are new to LabVIEW, please take a look at this short three hour tutorial that can help you get started with LabVIEW programming: http://zone.ni.com/devzone/cda/tut/p/id/5243.

The LED color can be changed using a property node. Take a look at both the program and the tutorial, and let me know if you need more assistance.

Have a great day, and best of luck on your application!!
