The BBC micro:bit is a pocket-sized codeable computer with motion detection, a built-in compass and Bluetooth technology. You can do some amazing things with Marty and Micro:bit working together through the Scratch 3 Web App.


As mentioned Micro:bit works with Marty via the Scratch 3 Web App. If you are not familiar with our Web App check out our user guide here. As part of the Web App process you will also need to connect your Marty to Wifi in which you can check out our user guide here.

Set Up

1. Follow the brilliant instructions at to install Scratch link and set up your micro:bit to be ready for Scratch

2. Power up your Marty, as you normally do, and the micro:bit, either via the USB cable connected to your device or the battery pack.

3. Load the Scratch 3 Web App

4. Connect your Marty as normal using the connect/configure tab. (see instructions here)

5. Connect your micro:bit by clicking on the Add Extension button in the bottom left.

6. Find the micro:bit extension

7. Select your device from the list and press connect. It is important that Scratch Link is running at this time! The set-up is complete. (For instructions on setting up Scratch link press here)

Ok! Now that we are set up, let's start with something super simple and get our Marty, micro:bit, and Scratch 3 working in perfect harmony. Look in the micro:bit blocks section, at the bottom of the Scratch sections, and the Motion section to find these blocks and connect them together. (Note that normally, in Scratch, code is run when the green flag is pressed; however, in this case, code is run when the micro:bit is interacted with: the green flag is always on.)

When you press the 'A' button on the micro:bit, Marty will get ready and wiggle his eyebrows! Marty has responded to a command from your micro:bit!

Try experimenting with what you can do with Marty and micro:bit.
