14. Laser Module(EF05013)#
It is made of a laser emission chip, condensing lens and an adjustable sleeve, which can work after powering on.
Designed in RJ11 connections, easy to plug.
|Type of Connection||Digital input|
|Spot Size||φ10mm ~ φ15mm at 15 meters away|
14.6. Quick to Start#
14.6.1. Materials Required and Diagram#
Connect the Laser module to J1 port and the Crash sensor to J2 port in the Nezha expansion board as the picture shows.
14.7. MakeCode Programming#
14.7.1. 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.
14.7.2. Step 2#
14.7.3. Code as below:#
The Laser module turns on while the crash switch being pressed or it turns off.
14.8. Python Programming#
14.8.1. Step 1#
Download the package and unzip it: PlanetX_MicroPython
Go to Python editor
We need to add enum.py and laser.py for programming. Click “Load/Save” and then click “Show Files (1)” to see more choices, click “Add file” to add enum.py and laser.py from the unzipped package of PlanetX_MicroPython.
14.8.2. Step 2#
from microbit import * from enum import * from laser import * laser = LASER(J1) while True: laser.set_laser(1) sleep(500) laser.set_laser(0) sleep(500)
The Laser module lights on for 500ms and then lights off for 500ms after powering on.
