Arduino read digital input always 1

5 views (last 30 days)
I'm trying to read a digital input in simulink and then activate the 13 led pin of my arduino MEGA via a digital output. My problem is that the input is always 1, no matter if I push the button or not. How can I solve this?
Thanks in advance and regards,

You can click the the "Deploy to hardware" button as described in the Run Model on Arduino Hardware topic.
One common error is to click the "Run" button (green triangle), which simulates the model on your host computer. The input is always 1 because they do not exist on the host computer.
Hope it helps !

Ok, i will try this!
One question, monitor and tune option is used to simulate on your hardware your code while simulink is monitoring all the inputs and outputs, Im right?
