Metaconta:
Hi:The table above is a combination of resistance 8 levels that controls Arduino. This adjusts the motor speed.
In my case I only need 4 levels of speed to the motor with 2 optocouplers.
Motor speed is used only at the end of the laundry, after the motor speed used in the spin cycle.
Greeting.
Yeah, they're just the means by which the user interface communicates with the microcontroller, ie the means by which the microcontroller receives speed commands. The resistances have nothing to do with motor control; the speed of the motor is controlled by varying power to it through variable timing on the triac trigger pulses as I described above. Again, this is not something you should attempt at this point.
