This article is about the extension in Scratch 3.0 and Scratch 2.0. For the older version of WeDo, see LEGO WeDo 1.0 Extension. For the extension in Scratch 1.4, see Motor Blocks.

The LEGO Education WeDo 2.0 Extension is an extension in Scratch 3.0 and Scratch 2.0. It lets projects interact with the Lego WeDo Construction Set 2.0.

Blocks

Scratch 3.0 contains six Lego Education WeDo 2.0 stack blocks, two hat blocks, two reporter blocks, and one boolean block.

• turn ( v) on for () seconds
• turn ( v) on
• turn ( v) off
• set ( v) power to ()
• set ( v) direction to ( v)
• set light color to ()
• when distance ( v) ()
• when tilted ( v)::wedo
• distance::wedo
• tilted ( v)?::wedo
• tilt angle ( v)::wedo

Removed Block

The play note ( v) for () seconds was a stack block available for use in Scratch 2.0, but was removed in Scratch 3.0 due to unknown reasons. If the block is imported into Scratch 3.0 from a Scratch 2.0 project, the block functions as expected.

Connecting a LEGO WeDo 2.0 Set

To connect a WeDo set in 3.0, a Scratcher must go to the extensions menu. From there, click on the LEGO WeDo 2.0 extension. A pop up will appear with the option to start searching. When the button is clicked, it begins looking for WeDo sets via Bluetooth. To connect a WeDo set, one needs to install Scratch Link. It can be installed here.

Connecting in 2.0

This article or section documents something not included in the current version of Scratch (3.0). It is only useful from a historical perspective.

To connect a LEGO WeDo set in 2.0, a Scratcher must go to more blocks then click 'add extension', then from there select WeDo 2.0. The plugin must be downloaded onto the computer. A traffic light system will show if the set has been connected.
