Would someone kindly direct me to help achieve the following result.
Which would be the simplest way, if any, by either hardware or software implementation, to turn a flow sensor 5/2.5/0-volt pulsation into a 5-v if rotating or 0-volt if not. Basically, making the flow sensor pin, whichever, on the Arduino a high or low state.
This would be my ideal for the next line of the program.
