Double Solenoid won't move

[mwong]

We're coding in Java, we've made two Solenoid objects which are connected to the joystick. The lights on the solenoid breakout turn on and off, and so do two lights on the double solenoid. However, the solenoid doesn't move in either direction when one side is on and the other side is off.

One bizarre thing is that we get the same effect when we spin one of the connectors in the solenoid breakout 180 degrees, switching the signal and ground wires.

The solenoid works perfectly when manually activated, so we know that our air tubing is fine.

Has anyone succeeded in controlling their double solenoid with code? We've reached a dead end.

Thanks,
