27.5. Outlook

27.6. Quick to Start

27.6.1. Materials Required and Diagram

Connect the Dust sensor to J1 port and the OLED to the IIC port in the Nezha expansion board as the picture shows.

27.7. MakeCode Programming

27.7.1. Step 1

Click “Advanced” in the MakeCode drawer to see more choices.

We need to add a package for programming, . Click “Extensions” in the bottom of the drawer and search with “PlanetX” in the dialogue box to download it.

Note: If you met a tip indicating that the codebase will be deleted due to incompatibility, you may continue as the tips say or build a new project in the menu.

27.7.2. Step 2

27.7.3. Code as below:

27.7.5. Result

The value detected by the Dust Sensor displays on the OLED screen.

27.8. Python Programming

27.8.1. Step 1

Download the package and unzip it: PlanetX_MicroPython

Go to Python editor

We need to add enum.py and dust.py for programming. Click “Load/Save” and then click “Show Files (1)” to see more choices, click “Add file” to add enum.py and dust.py from the unzipped package of PlanetX_MicroPython.

27.8.2. Step 2

27.8.3. Reference

from microbit import *
from enum import *
from dust import *

dis = DUST(J1)
while True:
    display.scroll(dis.get_dust())
    sleep(500)

27.8.4. Result

The value detected by the Dust Sensor displays on the micro:bit.
