Our project

The “Smart Bin for Waste Sorting” project uses a micro:bit to sort waste into organic, inorganic, and recyclable types. A servo motor helps open and close the bin lids automatically.

The project is for students and people who care about the environment. It can be used in schools, parks, and neighborhoods to reduce mixed waste, support recycling, protect the environment, and help people learn more about waste sorting.

We had some challenges, like adjusting the servo motor, training the AI, and finding the right power source. But we solved them by testing and improving the design.

We are proud that our project uses technology to create a real, useful, and eco-friendly solution to help fight climate change.

Our inspiration

The students were inspired by their growing awareness of environmental pollution and climate change, which are directly affecting daily life. They noticed a large amount of waste at schools and in residential areas that were not properly sorted. This led to pollution and wasted resources.

At the same time, they had access to modern technology like the micro:bit and AI. They wanted to use scientific knowledge to create a solution that is both practical and educational.

Their strong desire to protect the environment and build a more sustainable future also gave them great motivation — especially when they realized that they could make a real, positive impact in their community.

Our project helped us learn more about the micro:bit board. We also learned how to work well together as a team. At the same time, we hope to help save electricity and protect the environment.
