Click "Extensions" in the bottom of the drawer and search with "PlanetX" in the dialogue box to download it. ![](./images/05001_05.png) ***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. ### Step 2 ### Code as below: ![](./images/05017_06.png) ### Link Link: [https://makecode.microbit.org/_7bYWKYccY73R](https://makecode.microbit.org/_7bYWKYccY73R) You may also download it directly below:
### Result The icons display on the micro:bit accordingly with the order given by pressing button A or B or A+B. ## Python Programming ### Step 1 Download the package and unzip it: [PlanetX_MicroPython](https://github.com/lionyhw/PlanetX_MicroPython/archive/master.zip) Go to [Python editor](https://python.microbit.org/v/2.0) ![](./images/05001_07.png) We need to add enum.py and button.py for programming. Click "Load/Save" and then click "Show Files (1)" to see more choices, click "Add file" to add enum.py and button.py from the unzipped package of PlanetX_MicroPython. ![](./images/05001_08.png) ![](./images/05001_09.png) ![](./images/05017_10.png) ### Step 2 ### Reference ``` from microbit import * from enum import * from button import * button = BUTTON(J1) while True: if button.A_is_pressed(): display.show(Image.HAPPY) elif button.B_is_pressed(): display.show(Image.SAD) elif button.AB_is_pressed(): display.show(Image.COW) sleep(500) ``` ### Result The icons display on the micro:bit accordingly with the order given by pressing button A or B or A+B. ## Relevant File ## Technique File
