I am trying to make a wireless controller for 6 linear actuators

Projects General Guidance
1

I want to control 6 linear actuators from a wireless remote control. I want the control to have 6 buttons, one for each linear actuator. I just want the linear actuator to full open when pressed, and then press again to fully retract.

I have been playing with some relay boards but I am having trouble figuring out how to reverse the polarity to get the retract to happen without having to flip a switch.

Thank you!

These are the actuators that I am eyeing, but I am open to others

I have a few candy bars and I want to go to the moon tells me about as much as you did about your project. We cannot see what you have and there are thousands of different actuators that I can chose from.

Please keep in mind that we are not a free design or code-writing service. We’re more than happy to help with your design or code, but we need you to make an initial attempt. Please design and write your code, then post it along with an explanation of what’s not working properly.

  1. Show Your Work First: Before asking for assistance, make an attempt to design or write the code yourself. Share your work along with details about what isn’t working.
  2. Provide Clear Documentation: Since we can’t see your project, share an annotated schematic (best) or a clear drawing of your setup. Pictures are welcome, but avoid using Fritzing diagrams as they are wiring diagrams, not schematics, and are not ideal for troubleshooting.
  3. Include Technical Details: If there is specific hardware involved, include links to technical information. There are often many versions of similar components, so precise details are essential.
  4. Reference Resources: For additional help, check out useful links and tutorials: Useful Links on Arduino Forum.

how do you know when the actuator is fully open/closed, e.g. limit sensors, measure current, etc???

If you are using the linear actuators internal limit switches as the end stops for the actuator movements, all you need is one DPDT relay per actuator configured as a polarity swapping arrangement.

Post a link to the actuators' datasheet.

Try one of these..........

You could use 2 SPDT relays wired like this, replace motor(M1) with actuator.
