Servo on joystick

[apalrd]

There's actually an easier way then that. Go into (I think it's Comparison) palette and look for a Switch. I forgot it's exact name, but basically it looks like a triangle with a T and F inputs on the top and bottom and a case on the middle. It just passes the data through depending on the value of the input.

I don't really use lab view, but that sounds like a logic gate

in c++ you could do some thing similar with a boolean variable:

int main()
{
   bool virtualdigin1;
   if digin1==1
     {
        virtualdigin1=0;
      }
   else
     {
        virtualdigin1=1;
      }
}

It is. The solution proposed by Bill is a case structure, I proposed a switch.

Here is a picture of what Apalrd suggested. He is right, it is even easier than what I suggested.

Not that it won't work, but controlling a button with a servo seems like it's adding additional potential points of failure unnecessarily.Servo controlled features do have their place, but i'm not sure this is it.

If the servo and button are on 2 separate systems, then I suggest a relay instead of a button that must be physically connected with the servo and then made to work together.

on the other hand, if the system controlling the servo also receives the input from the button, the issue could probably be fixed in programming.

However, if you still feel these solutions won't work and you need some sort of electromechanical actuator, a solenoid might be better (assuming this isn't ON the robot, if it is, the input from the button and servo output are both handled by one system so you should fix it in the code)

of course, since this is a black project there could be some major detail I don't know about that makes this your only option, in which case, disregard this.

Controlling a button with a servo? I think you have it backwards. I hope you have it backwards. I'm pretty sure the question was how to control a servo with a joystick button.

I hope you are right Alan, I was going an the same assumption.

Although, when you read the OP's original question, you can see why there is room for confusion.
It's amazing how our language can open to so many different interpretations.
