Arduino as Washing Machine Controller

That is exactly what i meant in my reply.
One shouldn't compare or reflect its own situation to that of other, less fortunate countries.

Did you have an actual question, or are you sharing your experiences so far ?

All the wires to the motor, are to enable different speeds, so the same motor can (and will) be used to spin.
I can't tell you exactly how this works, but it's unlikely that there's just an extra motor coil that will be added, as most machines have multiple spin speeds.
So there needs to be some logic to it.

If you do have questions, telling the model of the Whirlpool machine might come in handy, or tell us anything else you can find out about the controller board (like any stickers or other clues to the model).
