To be clear, the opencpn pypilot plugin does not run the autopilot, it simply communicates with pypilot for control and configuration and integration purposes.
The rudder feedback resistor does not need a specific value because the signal is an analog voltage, not a resistance. So depending on the settings this will range from 0-5 volts or 0-1.1 volts. The arduino itself can only supply maybe few dozen milliamps, but it's better to not use too much. So a 5k-10k potentiometer is recommended, or a hall-effect sensor with analog output is even better because it won't wear out.
