I am working on a project where I need 2 solenoid valves; both are N/closed and exactly the same. Only one will be open at a time, or both will be closed.
I am using this schematic which works fine for one solenoid valve: http://www.arduino.cc/playground/uploads/Learning/solenoid_driver.pdf
I want to use the same power supply for both solenoid valves. Can anyone provide a rough circuit diagram for this?
Many thanks, Ross
