- This article is about the device. For the extension, see micro:bit Extension.
The micro:bit is a small computer designed by the BBC for use in schools: a small circuit board with lights, buttons, and tilt/movement sensors. The micro:bit extension allows it to be used with Scratch.
Connecting a micro:bit to Scratch
To connect a micro:bit to Scratch, the micro:bit extension must first be added. Scratch will then try to find a micro:bit connected to the computer. If one is not found, a window will appear telling the user to make sure the Scratch Link app is installed and running along with telling the user to make sure that Bluetooth is on. However, if using Scratch Desktop with Scratch Link open and Bluetooth, on it just says no devices found.[clarify]
The micro:bit has the following features that Scratch does not support natively:
- Tilt/movement sensor: Changes the tilt values and triggers jumped and shaken events.
- 5×5 Display: A 5×5 grid of lights that can show text and small images.
- Buttons: Can be pressed to trigger the button pressed hat.
- Pins: 25 pins that can be connected to other things.
