MakeCode Programming​

Step 1: How to Add Jacdac Extension​

  1. Go to Microsoft MakeCode and click "New Project".

  1. Enter the project name in the pop-up window and click "Create".

  1. Click "Extensions" in the code drawer.

  1. Enter "Jacdac" in the pop-up interface, click the search icon, and select the Jacdac library as shown.

Step 2:​

  1. Connect the micro:bit to the computer with a data cable. Note: If the micro:bit runs a Jacdac program for the first time, please pre-install a blank Jacdac program on the micro:bit first; otherwise, skip this step.

  1. Connect the sensor. MakeCode will automatically recognize it and simulate its status in real time in the simulation area.

  1. Click "ADD BLOCKS" for the sensor extension module. Note: When connecting a new sensor, repeat the operation of clicking "ADD BLOCKS" for the sensor extension module.
