Bit of Advice Needed Motors and Motor Shield.

Hi

I want to power 3 motors from a Arduino Nano, but I don't have a lot of experience with electronics
and was hoping to get some idea's of what I would need to do it.

I want to control a DC Motor with a high RPM and descent torque and 2 Stepper / Servo motors.

So I thought that this would be possible using a Shield, and an external PSU to power the motors ?

Can anyone recommend a Shield That will do this ?

And also a PSU that will run it ?

You know what it's like when you get an idea to do something, but don't have the knowledge to do it
and it in the back off your mind and keeps popup up every now and again, this is one of them times.

Thanks in Advance For any help you can off.

Regards

Potman
