15. Motor Fan Module¶
It is a simple motor-drived fan module.
Designed in RJ11 connections, easy to plug.
|Type of Connection||Analog input|
15.5. Quick to Start¶
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.
15.6. MakeCode Programming¶
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.
Code as below:¶
The rotation speed of the fan is adjusted by the potentiometer.
15.7. Python Programming¶
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.
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.
