arduino water flow control
The water flow sensor is integrated with a magnetic hall effect sensor, which generates an electric pulse with every revolution. This function is an interrupt service routine and this will be called whenever there is an interrupt signal at pin2 of Arduino UNO. You might apply 12 V to actuate, but then you can reduce the voltage very low (maybe 2 V or lower) and the valve will still say actuated. Why is the comparative of "sacer" not attested? Connect and share knowledge within a single location that is structured and easy to search. The sensor has 3 wires RED, YELLOW, and BLACK as shown in the figure below.
