@starsandrobots electronics question: I have a 12v DC motor I want to control programmatically. Need to run it forwards and reverse. (cont)
-
hm ok. Can you accept powering the motor with half the current? (Half the torque?)
the process of what you need to do is boost 12V to 24V and create a virtual ground at +12V, which the WeMo controls.

I am checking out WeMo now also
-
alternately depending on how heavy the door is, see if +/- 6V is tolerable, or buy a servo to use instead
-
it's a worm drive door so I suspect reducing voltage just means it opens more slowly.
-
but I'm lost as to what I'd need to set up the virtual ground. Links to stuff to read?

then you have +12V and -12V to work with
-
note that I also need to be able to supply 0V (stop the motor). Maybe use a different WeMo switch for that :)
