MakeCode Programming
Step 1: Adding the Jacdac Extension
- Go to Microsoft MakeCode and click New Project.
- Enter a project name in the pop-up window and click Create.
- Click Extensions in the code drawer.
- Type "Jacdac" in the search bar, click the magnifying glass icon, and select the Jacdac software library as shown.
Step 2:
- Connect the micro:bit to your computer using a data cable. Note: If this is the first time running a Jacdac program on the micro:bit, preload a blank Jacdac program first. Skip this step if already done.
- Connect the sensor. MakeCode will automatically detect it and simulate the sensor status in the emulator.
- Click ADD BLOCKS for the sensor extension module. Note: Repeat this step each time you connect a new sensor.
