Or use Scratch to turn on a motor

Before you begin: If this is your first time ever using Scratch software, start  Getting Started with Scratch.

You can use the LEGO WeDo distance sensor to interact with characters on the screen.

Step 1: Get the sensor working.

WeDo hub and distance sensor
Plug the hub into your computer, and the distance sensor onto the hub.


Make sure it's the distance sensor.

It looks like it has two "eyes."
