Hello, I have a question: Can the Arduino control a 3-phase machine with 8 motors? Control is through connecting sensors to reverse the movement of the motors and other commands.
Probably, but you'll need to know something about the motor controllers/drivers. Or, maybe there are relays. (The Arduino can't directly drive a relay coil, but you can built a driver circuit).
The Arduino itself is, of course, low voltage and low current. But with relays or optical isolation it can control more powerful loads. (The lethal voltages MUST be electrically ISOLATED.)
Probably it depends on how complicated the control algorithm is, if there are time constraints, what is in your tool kit and experience. Using the wrong interface design can fry both the Arduino and you. If you do not have experience with these motors and voltages get some expert help, it may keep you alive.
