USES AND APPLICATIONS OF MICRO:BIT IO EXPANSION BOARD:

What is the Micro:bit IO Expansion Board?

It is a board that allows us to connect multiple sensors to our Micro:bit, expanding the range of projects we can undertake with it. Please note that when using MakeCode or any other application, you must configure it to function correctly. Configuration should be done within the block option - PIN. It will not work properly without proper configuration.

Micro:bit PIN IO Configuration:

The best feature is its size. It is a compact-sized board, ideal for educational robotics projects.

Thanks to this board, we can use sensors up to 5V. For example, it supports multiple small 9g servos.

It is easy to use as it mimics the Micro:bit pins, allowing us to use crocodile cables with it.

It's important to note that this board cannot read or write to regular IO ports since the bottom of the Micro:bit is dead. In the SPI cable ports (14, 15), the IO port is readable and writable.

EXERCISES IN CLASS:

• Connect different sensors and demonstrate how to read data using Micro:bit.
• Create a simple project using the built-in buzzer for sound feedback.
• Explore I2C functionality using pins 19 and 20 for specific sensors.
• Integrate the board with LEGO-compatible components to build interactive projects.

EXERCISES AT HOME:

• Design a personalized project using the Micro:bit IO Expansion Board and present it in class.
• Experiment with different sensors and document their functionalities in a project journal.
• Create a simple game or interactive application using the board's features.

WHAT WE CAN LEARN:

• Understanding and implementing pin configurations in Micro:bit.
• Exploring the use of sensors for data acquisition.
• Building projects that involve sound feedback with the built-in buzzer.
• Practicing programming skills through project development.

WHAT IS MICRO:BIT?

Micro:bit is a pocket-sized computer that introduces children to programming and electronics. It is designed for educational purposes, allowing students to engage in creative and hands-on learning experiences.

WHAT IS IO AND WHY IS IT IMPORTANT TO KNOW?

IO stands for Input/Output. In the context of the Micro:bit IO Expansion Board, it refers to the ability to read and write data to different ports. Understanding IO is crucial as it enables users to interface with various sensors and components, expanding the capabilities of the Micro:bit.

WHAT IS EDUCATIONAL ROBOTICS?

Educational robotics involves using robots as educational tools to facilitate learning in various fields such as programming, engineering, and problem-solving. It provides a hands-on and interactive approach to education, fostering creativity and critical thinking skills.
