This video demonstrates a simple Scratch game (Apple Grab) designed to work with the BBC micro:bit as a remote controller. See link here https://scratch.mit.edu/projects/156186854/#player .
To make the game work you will need
1. A BBC micro:bit
2. The S2Bot 4 Scratch plugin for the Chrome browser which can be installed from here https://chrome.google.com/webstore/category/extensions?utm_source=chrome-ntp-icon . Just search for S2Bot 4 Scratch
3. A Bled112 bluetooth dongle which enables your micro:bit to communicate over bluetooth with your computer and Scratch. See here http://www.picaxe.com/BLED112-Bluetooth-USB-Dongle/ .
The Apple Grab game was originally created by my colleague Jeremy Burton. I have developed the game and controller for a primary teacher education module on Physical Computing taught to undergraduate computing specialists on a 3-year Primary ITE course.
The 3D printed container and lid for the BBC micro:bit was designed by Rob at the University of Brighton. See link here https://www.myminifactory.com/object/micro-bit-box-lid-round-31927 .
