Here is a link to the 12 VDC, 10 Amp linear actuator made by firgelli auto that I am referring to ...http://www.firgelliauto.com/product_info.php?cPath=69&products_id=248I believe it just uses a servo motor. Correct me if I am wrong, but I was reading something yesterday that said I could use some sort of relay and transistors that could convert the 5V from the arduino to 12V needed by the actuator. Is this true or would I need a separate power supply for each one?
If I use the relay, would the actuator be powered from the arduino or from an external power supply? and If I use a 10+ Amp H drive motor driver then does that mean the arduino is able to provide 10A to the actuator? bear with me on this since I am slowly trying to understand all this
