Hello, I am interested in determining if my arduino uno can generate a signal equal to a hall effect switch. I need to feed a hall effect signal into a fuel injector control module as the cam position sensor would in a diesel engine.
Not too sure I understand what you are asking because it seems too easy.
The output signal from an arduino will look like the output signal of a hall effect switch powered from 5V.
However you need to know what voltage your fuel injector control module needs.
