A relay is a digital output. Can anyone give me an example of when digital in would be used? Can a victor be used as a substitute for a spike(I don't need variable speeede)? I think that a realy has to give 2 1/2 values: 0, 1, and -1. The negative 1 come in when you want the motor to go reverse. The trigger on ly returns 0 or 1, but when it is processed through relay1_rev, it must somehow be inverted to allow the motor to go backwards. Is a PWM cable legal for digital i/o? Shouldn't it just be called a data cable then?
