although I believe it is possible to run a reprap on an arduino uno, I think it will be a lot more hassel than it is worth.
However if all you have left to do is power the hotend, you just need a suitable mosfet attached to a digital pin.
dont forget that you also need to read something like a thermistor to control the temperature.
