Laura HaaimaElectric solenoid door lock 12VDCI have it working, but it interferes great with the Sparkfun relay. Or the relay does not switch strongly enough on an Arduino output of 3 volts
Anonymous5V / 12V Waterpump 240L/HWorks perfectly on 12 volts, I couldn't get it to work with 5 volts. The packaging also only says 12 volts, so that may be an error in the description. A good service!
