LEGO + Vernier Go direct
Here are some example projects that combines LEGO and Vernier sensors. With LEGO's robust building system and Vernier's wide collection of precise sensors, these projects show the possibility to develop fun, informative learning experiences with the two platforms. For each example there are videos, LEGO building instructions, .io files, as well as CAD files (.stl and Solidworks) for 3D-printing the connecting pieces.
Force and Acceleration Sensor (GDX-FOR)
LEGO Gear Trains
Photogate Sensor (GDX-VPG)
