Using micro:bit for building distributed sensor networks in robotic systems

Purpose. The purpose of the paper is to explore the possibilities of integrating the micro:bit microcontroller with external devices through UART, I2C, and SPI protocols to create modular and distributed sensor networks in robotic systems. The article focuses on the compatibility issues of these protocols with other devices and possible solutions. Design / Method / Approach. The paper uses an experimental approach, examining the use of standard communication protocols to connect micro:bit with external sensors and controllers, such as Raspberry Pi, to build a modular sensor network. Findings. It was found that micro:bit supports all major communication protocols, but there are compatibility issues with the radio protocol and external devices. UART, I2C, and SPI allow micro:bit to integrate with a wide range of sensors and devices, but additional configuration is needed for stable operation. Theoretical Implications. The article demonstrates that the use of standard protocols for integrating devices into robotic systems is a key aspect of creating modular sensor networks. It shows that micro:bit can be an important component to developing such systems. Practical Implications. The results can be applied in educational projects and for the creation of modular robotic systems where micro:bit acts as a manager module of different sensors. This expands the potential use of inexpensive microcontrollers in real-world scenarios. Originality / Value. The article contributes to research on integrating micro:bit into robotic systems, which is important for educational robotics, as it shows new possibilities for using microcontrollers in distributed systems. Research Limitations / Future Research. The limitation of the study is that it is based on theoretical assumptions about protocol stability when connecting multiple modules. Future research should focus on real-world testing of compatibility with other devices and optimizing wireless communication. Paper Type. This is a technical note with both experimental and theoretical elements, explor-ing the issues of integrating micro:bit into distributed systems. PURL: https://purl.org/cims/2403.013
