Micro:bit Explorer

Explorer BBC micro:bit sensor data and inputs over BLE

See the Explorer online: https://microbit-explorer.ok-y.xyz

Quickstart

Micro:bit Explorer

to run locally

yarn install
yarn dev

micro:bit

to prepare the micro:bit follow the following steps:

1. Open MakeCode
2. Import a project from the .hex found in doc/microbit/microbit-basic_ble.hex OR create a new project and copy and paste the python code in doc/microbit/microbit-basic_ble.py to the MakeCode python editor.
3. Connect micro:bit with USB cable and download the project to the micro:bit

For more info about how to program and work with the micro:bit see one of the many MakeCode tutorials on the MakeCode.
