Automatic Recycle Bin

Complete

Inspiration The idea came while eating lunch, we noticed many lunch boxes being wasted. That inspired us to reuse them to build an eco-friendly automatic trash can that keeps hands clean and promotes recycling.

How We Built It

Arduino Board: Acts as the brain that processes input from sensors and controls all components.

Ultrasonic Sensor (HC-SR04): Detects when a person or hand is near.

Servo Motor: Opens and closes the lid smoothly based on sensor readings.

LCD Screen: Displays recycling messages and prompts.

Buzzer: Provides sound feedback for user interaction.

Cardboard Body: Made from reused lunch boxes to reduce waste and cost.

What we Learned We learned how to connect and program multiple components using Arduino, troubleshoot circuit issues, and integrate both hardware and software effectively. We also learned the importance of sustainability and creative reuse in engineering projects.

Challenges Faced We faced several challenges: getting stable readings from the ultrasonic sensor, synchronizing the servo movement, wiring all components properly, and ensuring the LCD and buzzer worked together. We learned that by working with hardware, you not only have to watch out for coding bugs, but also physical issues with components that can throw off your results. It took time and many trials, but through perseverance and determination we pushed through and learned a lot in order to complete this project

Our project combines automation, hygiene, and sustainability to make everyday life easier.
