I'm guessing +5V would be my +5v of the power adapter.And I would connect the volt-meter to it too.Gnd would be my -5 volts of the power adapter.And the one marked "to an analog input would be connected to the volt-meter's other cable.Correct?
So if I did the setup in http://www.libelium.com/squidbee/index.php?title=Adding_a_light_sensor without the Arduino (just a 5 volts + and a 5 volts - taken from an old power adapter I hacked).
