Introduction

The Micro:bit is not just a tiny circuit board. It is a powerful tool packed with various sensors that allow users to interact with it in different ways. In this article, we will explore the capabilities of the Micro:bit and learn how to create a fun electronic version of the magic 8-ball using this versatile device. We will also cover topics such as saving and sharing Micro:bit projects, as well as making the project more portable.

What is the Micro:bit?

The Micro:bit is a small development board designed to introduce students to the world of electronics and programming. It was created as a collaborative project between various organizations, including the BBC, Microsoft, and the University of Lancaster. The Micro:bit is equipped with an ARM-based microcontroller, as well as a range of sensors and LEDs.

Micro:bit Features

The Micro:bit comes with several features that make it versatile and suitable for a wide range of projects. Let's take a closer look at some of its key features:

3.1 Accelerometer

The Micro:bit features an accelerometer that measures motion. This sensor allows the Micro:bit to detect movement in three axes: X, Y, and Z. By utilizing the accelerometer, we can create projects that respond to shaking or tilting actions.

3.2 Compass

Another handy sensor on the Micro:bit is the compass. This sensor enables the Micro:bit to determine the direction it is facing. By utilizing the compass, we can create projects that respond to changes in direction or orientation.

3.3 Temperature Sensor

The Micro:bit also includes a temperature sensor, which can measure the ambient temperature. This sensor allows us to incorporate temperature-based interactions into our projects, such as triggering certain actions when the temperature reaches a certain threshold.

3.4 Light Sensor

The LEDs on the front of the Micro:bit can also function as light sensors. This means that the Micro:bit can detect the level of surrounding light. By utilizing this feature, we can create projects that respond to changes in light intensity or implement ambient lighting effects.

Creating an Electronic Magic 8-Ball

4.1 Getting Started

To get started with creating an electronic version of the magic 8-ball, we will need a Micro:bit and a USB cable to connect it to a computer. Once connected, we can head to the MakeCode website, which provides a user-friendly interface for coding the Micro:bit.

4.2 Coding the Micro:bit

In order to program the Micro:bit to function as a magic 8-ball, we will utilize the accelerometer and a random number generator. By shaking the Micro:bit, we can trigger a response based on the value generated by the random number generator. The code can be written using blocks and snapped together in the MakeCode editor.

4.3 Testing the Magic 8-Ball

Once the code is written, we can test the magic 8-ball by pressing the shake button on the MakeCode simulator. We should see one of the predetermined messages scroll across the screen, simulating the response of the magic 8-ball. This allows us to verify if our code is functioning as intended.

Saving and Sharing Micro:bit Projects

5.1 Saving Projects

To save our Micro:bit projects, we have a few options available. One way is to simply rename the project at the bottom of the MakeCode page. This will save the project locally on our computer and associate it with our browser. However, if we need to switch computers or browsers, the project will not be accessible.

5.2 Sharing Projects

If we want to share our Micro:bit projects with others or open them on a different computer, we can use the Save button next to the project name. This will download a .hex file, which can be shared via email, cloud storage, or any other file transfer method. Recipients can then import the .hex file into the MakeCode editor to access and modify the project.

Making the Project Portable

6.1 Powering the Micro:bit

To make our Micro:bit project more portable, we can disconnect it from the computer and power it with a battery pack. By using a power source such as two AAA or AA batteries, we can take our magic 8-ball on the go and use it without being tethered to a computer.

6.2 Enhancing the Magic 8-Ball

To enhance the functionality of our magic 8-ball, we can add more responses to the list of messages. By increasing the number of possible responses, we can create a more diverse and engaging experience for users. Additionally, we can get creative and personalize the messages to suit our preferences or specific themes.

Conclusion

The Micro:bit is a versatile tool that allows users to explore the world of electronics and programming. By utilizing its various sensors and features, we can create interactive projects such as an electronic magic 8-ball. With the ability to save, share, and make projects portable, the Micro:bit provides a platform for learning and innovation.
