Designed in RJ11 connections, easy to plug.
|Type of Connection||Analog input|
15.6. Quick to Start#
15.6.1. Materials Required and Diagram#
Connect the Motor fan module to J1 port and the potentiaometer to J2 port in the Nezha expansion board as the picture shows.
15.7. MakeCode Programming#
15.7.1. 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.
15.7.2. Step 2#
15.7.3. Code as below:#
The rotation speed of the fan is adjusted by the potentiometer.
15.8. Python Programming#
15.8.1. Step 1#
Download the package and unzip it: PlanetX_MicroPython
Go to Python editor
We need to add enum.py and fans.py for programming. Click “Load/Save” and then click “Show Files (1)” to see more choices, click “Add file” to add enum.py and fans.py from the unzipped package of PlanetX_MicroPython.
15.8.2. Step 2#
from microbit import * from enum import * from fans import * fans = FANS(J1) while True: fans.set_fans(1,100) sleep(3000) fans.set_fans(1,50) sleep(3000) fans.set_fans(0) sleep(3000)
After powering on, the Motor fan module rotates for 3 seconds at the speed of 100% first and then at the speed of 50% for another 3 seconds, and finally stops for 3 seconds.
