Hi there,Currently I have a LabJack U12 interface card and running LabVIEW 6.1. Connected to the LabJack card via the Analogue output port, AI0, is a light with dimmer circuitry. Within LabVIEW I am able to control the dimming of the external light by varying the voltage between 0-5volts. This is achieved using the "EAnalogOut.vi".What I would like to achieve is the lights being turned off automatically by some timer function within LabVIEW, by a time entered by the user of the application on the front form. I am unsure as to how to set the voltage applied to the external light to 0volts, which in turn would turn off the light, after a certain amount of time elapsing. Please find attached my vi.Any ideas on the matter would be greatly appreciated.Thanks in advance,Neil Sampson.
