Hi All,
I'm trying to building a device that would move back and forth with controllable frequency and magnitude. I'm would like to use either a servo or a linear actuator to do this (Firgelli Automations have decent onces). The linear actuators that I looked at so far would move forward if a postive voltage is applied and backward with change in polarity. Since I would like to make my device work for days, I would like to either purchase a circuit or an IC to do the change of polarity for me. I came across a circuit called a H brdige that would do that, but at this point I'm not sure how I can modulate how often the circuit would change polarity. If you know where I can buy such a circuit or if you would like to sugguest a better way to do what I'm trying to do, that would be great!!!
Thank you very much.
