RioRand (TM) 12V-40V 10A PWM DC Motor Speed Controller w/ Knob--High Efficiency, High Torque, Low Heat Generating with Reverse Polarity Protection, High Current Protection

Q: I have a Battery is UB1250 12VDC 5Ah and connect to Fan that is 12DC 3.90A, is your item does the same application as Rheostat? if this is Not the right One? which one you recommend please I look forward to your reply.

It is similar in function to a rheostat, however, it does not waste energy by dropping the current across a resistor. This devise uses Pulse Width Modulation. If you are not familiar with this function, it basically chops the voltage in order to regulate the current output. You will be able to control the fan speed, without loosing current through a resistor in a rheostat and wasting your battery. I use it to control 12 and 24 volt wiper motors for animatronic devices. I use power supplies instead of batteries and have digital meters for output voltage, current, and motor rpm feedback by attaching a 10 tooth sprocket to the motor shaft and sensing by means of PNP proximity sensor. All of this gives me the ability to monitor and control functions of the motor quite precisely. You can also purchase versions of this controller that allow PWM control of the speed instead of the potentiometer which will then allow programmed speed patterns with a micro controller such as Arduino. This will be my next project.

Q: Are there ports to screw the wires in or do they need to be soldered on?

There are four screw ports on the side opposite the controller knob. A pair for +/- power and another for motor. They are clearly marked on the under side of the board.

Q: How can I connect this to an Arduino to control a 12V motor?

I did it the brute-force way. I drilled a hole in the knob and inserted the shaft of a servo. I then controlled the servo via the Arduino. Not very elegant, to be sure, but nonetheless, effective.
