My power supply is capable of outputting a constant 30V. I run two motors at 30V wired in parallel and they draw about 1.85A so the internal resitance of that circuit should be about 16Ohms.
The thing is I want to make it a standalone unit so instead of requiring power for both the motors and the arduino, I wanted to power them both off of my 30V power supply.
I tried to make a voltage divider. I hooked 3 10Ohm resistors in series with the power lines for the motors. However I think I should've put the resistors after power was fed to the motors as I ended up frying all 3 resistors due to the insane power running through them.
Before I blow up any more resistors or my motor drivers, I would like some help as I am clearly out of my expertise.
So my question is, how should I wire my power circuit so my motors receive 30V and my arduino can receive 12V off of a 30V input. If it is helpful I can send my circuit diagram for what I attempted so far.
