Project Story
Inspiration
My inspiration came from the theme “Connected Worlds: Innovating Together”. Waste management is a global issue, and overflowing bins are common in many communities. I wanted to create a simple project that shows how technology can help connect people with waste management services, reduce pollution, and make cities cleaner.
What it does
The Smart Recycling Bin simulates a trash bin with sensors that track how full it is.
- At 85%, the system warns that the bin is almost full.
- At 100%, it alerts that the bin is full and calls waste management.
- If it goes beyond 100%, it reports an overflow.
This makes sure bins don’t spill over and waste management can respond at the right time.
How I built it
I built the project in Python. The bin’s capacity is set with a variable, and users can “throw trash” by entering numbers. Each input updates the bin’s fill level, which is calculated with:
[ \text{percent} = \frac{\text{filled}}{\text{size}} \times 100 ]
Conditional statements (if, elif, else) check the fill percentage and print the correct message. A loop allows the bin to reset and simulate multiple trash cycles.
Challenges I ran into
- At first, the program didn’t know how to stop or restart after the bin was full.
- I also had to figure out how to handle overflow (when the bin goes beyond 100%).
- Debugging indentation errors in Python was tricky too.
Accomplishments that I'm proud of
- I built a working simulation of a smart bin that connects to the waste management process.
- I learned to use loops, conditionals, and percentages in Python.
- The program became more realistic with “almost full” and “overflowing” alerts.
What I learned
- How to simulate real-world sensors with variables in Python.
- How to make a program loop for multiple cycles.
- That debugging is part of the process — every error teaches something.
What's next for Smart Recycling Bin
- Add real sensors (like ultrasonic sensors with Arduino or Raspberry Pi).
- Store data in a database so waste management can track usage.
- Create a mobile app that sends alerts directly to workers.
- Expand it into a network of connected bins across a community.
