Sorry Sander, i am unable to completely decode your query. But if i am right, you are requiring an isolated device which can be run without wall socket power. If so, then you can use recharge circuitry additionality or like solar power charging to your board if wall socket is not available. You can power your motor and Arduino from Battery then.

Hi Sander, for any battery powered application, the following points are very crutial

  1. You have to put your microcontroller into a Deep Sleep Mode, otherwise, the micro will suck the battery like a leach.
  2. You have to measure the consumed current and calculate the battery capacity needed for your application. 
  3. If you don't have access to wall power you can use a solar panel as debasis parida said.
  4. If you are thinking about putting a solar panel, you need to account for the voltage drop in the wire also.
  5. You can always use a swappable battery system which, which gives you a low battery indication.
