LEGO BOOST

The LEGO BOOST extension controls a LEGO BOOST Move Hub, including its motors, color sensor, and tilt sensing. It is built in and compatible with Scratch.

Load it from Add Extension and choose LEGO BOOST.

Requirements

BOOST connects over Bluetooth, so you need:

A computer with Bluetooth and a supported browser.
Scratch Link running to bridge Bluetooth to the browser.
The BOOST Move Hub paired with your computer.

Adding the extension opens a connection window to pair the hub.
