# 8x16 Matrix Module(EF05029) ## Introduction 8 x 16 Matrix module is a kind of 8 x 16 matrix screen that can display numbers, commonly used letters and symbols with scrolling-displaying function. ![](./images/05029_01.png) ## Products Link [ELECFREAKS PlanetX 8x16 Matrix Sensor](https://shop.elecfreaks.com/products/elecfreaks-planetx-8x16-matrix-sensor?_pos=1&_sid=de592d191&_ss=r) ## Characteristic Designed in RJ11 connections, easy to plug. ## Specification Item | Parameter :-: | :-: SKU|EF05029 Connection|RJ11 Type of Connection|IIC Working Voltage|3.3V ## Outlook ![](./images/05029_02.png) ## Quick to Start ### Materials Required and Diagram Connect the 8x16 Matrix module to the IIC port in the Nezha expansion board as the picture shows. ![](./images/05029_03.png) ## MakeCode Programming ### Step 1 Click "Advanced" in the MakeCode drawer to see more choices. ![](./images/05001_04.png) 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. ![](./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/05029_06.png) ### Link Link: [https://makecode.microbit.org/_H1Dec3A9iDDM](https://makecode.microbit.org/_H1Dec3A9iDDM) You may also download it directly below:
### Result The expresssions display on the 8x16 matrix module. ## 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 matrix.py for programming. Click "Load/Save" and then click "Show Files (1)" to see more choices, click "Add file" to add matrix.py from the unzipped package of PlanetX_MicroPython. ![](./images/05001_08.png) ![](./images/05001_09.png) ![](./images/05029_10.png) ### Step 2 ### Reference ``` from microbit import * from matrix import * matrix = MATRIX() x, y = 0, 0 while True: for y in range(8): for x in range(16): matrix.set_matrix_draw(x, y) matrix.set_matrix_clear() ``` ### Result Each LED lights on from the sequence of left to right and up to down, then they light off after all the LEDs light up. ## Relevant File ## Technique File
