Electronics (114 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. Most Powered Up hubs are controlled using Bluetooth, although there is also a basic battery pack can control up to two motors.

Earlier LEGO electronics include Power Functions (2007-2018), NXT/EV3 (2006-2020), 9V (1992-2013).
