I have a simple project.
I want to make a linear stage actuator move forward and backward when the actuator trips a proximity switch. What arduino product is best for this? I assume the simple starter kit would be good. Do I need an external power supply and what would be recommended?
What arduino product is best for this?
Any Arduino is capable.
I assume the simple starter kit would be good.
Good is not the same as necessary. There will be things you need that are not included. There will be things included that you don't need.
Do I need an external power supply
Yes.
and what would be recommended?
That you get one that is compatible with your linear actuators voltage and current requirements.
Do you need a linear actuator or would a motor and belt system work just as well?
What distance are you needing? What speed? What torque?
You will also need a motor driver compatible with the actuator's voltage and current requirements.
Seems like this project could be done without an Arduino by using two DPDT limit switches.
Thank you each for the replies.
I think the actuator is best (and it's already been purchased) because it is simple and I don't have to worry about torque/horizontal load. It also meets my physical needs (I don't have to build a structure for the belts, etc). My speed, torque, load needs are not much. I'm carrying about 15-20 lbs of vertical load and I need to move the actuator back and forth about 6 inches.
I currently have the actuator, a DC power supply and a stepper motor driver. From what I can see, this leaves me with nothing for control, which is why the Arduino Uno board might be just what I need. And, since I'm interested in what else I can use the Arduino for, I'm thinking about getting the starter kit.
