I AM USING A AUDRINO ANALOG INPUT PIN TO DISPLAY A VOLTAGE. WHEN I RUN THE MODEL ON TARGETED HARDWARE I ENDED UP GETTING ZERO. CAN ANY ONE HELP ME...

Hi Anil, It sounds like you clicked the Run (green triangle) button, which simulates the model on your host computer. Try clicking the Deploy to Hardware button instead. See http://www.mathworks.com/help/simulink/ug/run-model-on-arduino-hardware.html

my blocks being used are: Analog Input (pin 0). I have pin 0 on arduino connected to an analog input(a potentiometer with 0-5V in this case). Sample time = 0.5. A Display block. Short format. Decimation = 1. They are connected together.
Not sure why this isnt working.

HI Terry Ramsey, the external mode isn't work on the arduino uno. it will run on the arduino mega. they say uno doesn't have enough memory to perform in external mode.
i got this from matlab virtual seminor.

Hi Anil, the problem may be doing from 2 things:
1- you should be using arduino mega2560 for display a voltage.
2- You may be inverted the signal, because arduino is not accepted negative signal.

I had the same problem with arduino uno and I fixed it, just change the mode to external: simulation->mode-> external.
