Double Solenoid Help

We have a double solenoid hooked up to a piston
It is hooked up to relays 1 and 2
We are trying to make it come out when the trigger is pulled and go back when it is pulled again

What would I have to fix here?

Code:

int pnu = 0;

...........

       if(p3_sw_trig==1 && pnu==0)

        {

        relay1_fwd=0;

        relay1_rev=1;

        relay2_fwd=1;

        relay2_rev=0;

        pnu+=1;

        }



        if(p3_sw_trig==1 && pnu==1)

        {

        relay1_fwd=1;

        relay1_rev=0;

        relay2_fwd=0;

        relay2_rev=1;

        pnu=0;

        }

Re: Double Solenoid Help

Only have taken a quick glance at your code, but you can wire a double solenoid unsing just 1 spike. Look at the spike manual on ifirobotics.com to find otu how to wire. At will also make your code a bit easier

Re: Double Solenoid Help

We don't really have time to put a double on 1 spike, but is there a way to fix my code?

Re: Double Solenoid Help

To fix your code, you also need to make sure that you only process the change once each time the switch is activated.

Code:

  last_trig = 0;

  ...

  if (p3_sw_trig ==1 && last_trig == 0 && pnu == 0)

  {

    ...

    pnu += 1;

  }

  if (p3_sw_trig == 1 && last_trig == 0 && pnu == 1)

  {

    ...

    pnu = 0;

  }

  last_trig = p3_sw_trig;

Re: Double Solenoid Help

I added that, but for some reason I still can't get it working
