Hi! I have a large 6 story dollhouse that I want to build a motorized elevator for, but I'm having trouble finding parts & a tutorial. I was wondering if any of the parts/motors that are available from EZ Robot could be used to build one. Does anyone know? I want to be able to control it with a remote control and I would need it to stop at the right place for each floor of the dollhouse. Any help would be greatly appreciated! Thanks!
