  • I’m a little confused about powering these and an Arduino in the same project. If they draw up to 1 amp at 5 volts that’s probably pushing it for the Arduino’s 5V regulator output. So it would make sense to use a separate connection to the power supply with the Arduino controlling a transistor or relay. But if you’re using an external power supply for the Arduino, it’s probably 9 to 12 V which is probably too much for 5 V solenoids. So how do these facilitate working with an Arduino? Is the idea to use a 5 V regulated supply for the Adrunio (USB power input? bypass the regulator?) , that is also capable of delivering enough amps to power the solenoid in parallel?

No public wish lists :(
