I am using a 24v power supply for the solenoid valve. The solenoid valve is working if I directly connect it to a power source. It is also working when I remove the Arduino and only the MOSFET remains in the circuit. I also used a single-pole relay to drive the valve. It was worki...
A relay is a mechanical current-controlled switch. It consists of a coil, next to a piece of metal, that is pulled back by a spring. When current flows through the coil, it generates a magnetic field that attracts the piece of metal, and makes a connection. ...
