Electronics (33 parts)

Add light and motion to your creations using LEGO hubs, motors, lights, and sensors.

The current system for connecting electronics to a battery pack or hub is called 'Powered Up'. While there is a basic battery pack that can work with up to two motors, the majority of battery packs are bluetooth-connected hubs which allow you to create programs to control your model.
