2. Light Sensor(EF05001)#
This sensor aims to detect the light intensity in the current environment.
Designed in RJ11 connections, easy to plug.
|Type of Connection||Analog output|
|Size||55.8 x 23.8 mm|
2.6. Quick to Start#
2.6.1. Materials Required and Diagram#
Connect the light sensor to J1 port and the OLED module to IIC port in the Nezha expansion board as the picture shows.
2.7. MakeCode Programming#
2.7.1. 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.
2.7.2. Step 2#
2.7.3. Code as below:#
The light intensity’s value displays on the OLED module.
2.8. Python Programming#
2.8.1. Step 1#
Download the package and unzip it: PlanetX_MicroPython
Go to Python editor
We need to add enum.py and light.py for programming. Click “Load/Save” and then click “Show Files (1)” to see more choices, click “Add file” to add enum.py and light.py from the unzipped package of PlanetX_MicroPython.
2.8.2. Step 2#
from microbit import * from enum import * from light import * while True: light = LIGHT(J1) light_value = int(light.get_lightlevel()) display.scroll(str(light_value)) sleep(2000)
The light intensity’s value displays on the micro:bit.
