Lego Control Centre 9753.
Re-discovered I still had this which was last used for the TC ?? crane contest several years ago.

Has anyone used this for driving and controlling GBC modules ?

Think it has potential to run a Train GBC Gantry Crane module, to lift a ball hopper, traverse / lower (load balls)  raise / traverse / lower back onto train car.

Should be able to program the moments up / down left right for 3 motors but how to start the sequence automatically when a train car arrives & stop it when train departs.

The control centre has 3 outputs (Yellow / Red / Blue)  So red & blue used for the crane movements. Yellow to cause activate the train reverser for train to depart.

But is there anyway to detect a train arriving & start the sequence ?

p.s. posted is in the general Technic forum for now to reach a wider audience.

I think you would have to build some trigger mechanism to physically interact with the buttons.

BTW control center 2 also has an input jack for a 12v power adapter, making it even better for GBC. Because there is no feedback from the motors, the control center relies on timing. So if the batteries start to go just a bit low voltage, the motors won't move as far. So better to keep voltage constant by using an external power source.

Thanks, mine is the earlier version without a 12v input,  so looks like won't be suitable.
