Microbit Magnet

In the magnet challenge, I made a challenge using Microbit that behaved differently when a magnet is near the Microbit. 

The Microbit showed different images when I press the buttons in the Microbit.

For this activity, I used supplies as following:

Microbit 
Battery holder + 2x AAA Batteries
1x Magnet
1x USB Cable (To upload the code)
Also, I used Microsoft Makecode Software. 

Program using Makecode software

First, I opened the Makecode software. This is the page when I created new project. Do not forget to rename the project.

There are two choices for coding in Makecode, which are blocks and JavaScript. I chose block because it is easier to use.

Program the Microbit 

Here was my code. You could change the image as you desire. 

Test the code

To test the code, I unplugged the USB cable from the computer. For Microbit to standalone, I plugged in battery holder with the battery inside it.

Usually, the Microbit needs compass calibration. 

Tilt the Microbit to fill the screen. After that, test the code. When I pressed button "A" (the left button), and the magnet was far, it showed a cow image. 

While I pressed button "A" (the left button), and the magnet was near, it showed a giraffe image. 

When I pressed button "B" (the right button), and the magnet was far, it showed a duck image. 

While I pressed button "B" (the right button), and the magnet was near, it showed a target image.

I downloaded the code by clicking the download button and I connected the Microbit to the computer by plugging the USB Cable to the computer. 

Then, I copied the file that I downloaded previously into the Microbit . 

That is my entire project for magnet challenge. I hope you like it. Thank you very much for reading my tutorial.
