A project log for Washing Machine Conversion

Converting a Manual switched washing machine in to a Arduino powered smart washer.

Now for some code, I will add the final version later as there are a pile of additional timer routines but for now I am testing the stability of the system. There seems to still be some RFI issues when the spin cycle ends and the actuator drops the brake but I also ran out of parts to make a snubber for the actuator so this fault should go away once the additional snubber is n place.

Yes i know its full of while loops but I wanted this to be as simple as possible for testing purposes.
