Smart Waste bin - IoT Based Prototype

This is a fully functional Smart Waste Bin prototype developed as part of the CT101-3-3 Internet of Things (IoT) module at Asia Pacific University (APU) in 2024. The project received an A+ grade, showcasing excellence in both design and functionality.

An Arduino-powered Smart Waste Bin designed to improve waste management using IoT. It features a motion sensor for automatic lid opening, an ultrasonic sensor to measure waste levels, a visual indicator system (green/yellow/red LEDs), LCD display, and sound alerts for near-full capacity. Perfect for smart home or academic demonstration projects. Fully functional, with complete wiring, source code, and Thinkercad simulation included.

What included:
1) Arduino source codes
2) Thinkercad Simulation (shared link)
3) The physical Prototype

What the physical prototype includes:
🧠 Core Controller:
1× Arduino Uno Compatible Board (Maker Uno)

👀 Sensors:
1× HC-SR505 PIR Motion Sensor (for detecting user presence)
1× HC-SR04 Ultrasonic Sensor (for measuring bin fullness)

🖥 Display & Indicators:
1× 2x16 I2C LCD Display (shows waste level and status messages)
3× 5mm LEDs (Green, Yellow, Red for fullness indication)

🔊 Output Components:
1× Piezo Buzzer (alerts when bin is nearly full or lid opens)
1× SG90 Micro Servo Motor (automatically opens/closes lid)

🔌 Wiring & Power:
Jumper Wires (Male-to-Male and Female-to-Male)
1× USB Micro-B Cable (for power and code upload)

🔲 Breadboards:
1× Main Breadboard (2-line, for power and ground distribution)
1× Mini Breadboard (170-hole, for LEDs and resistors)

🧱 Structural Parts:
Custom Cardboard Waste Bin Structure
Cardboard Lid Attachment (servo-controlled flap)
LED Stand (cardboard mount for LEDs on front face)
Cutouts/holes for LCD, sensors, and components

🧰 Miscellaneous:
Resistors (3× 220Ω for each LED)
Rope/String (to connect servo to lid flap)
Glue/Tape (for component mounting)
Prototype wiring layout and build instructions

NOTE
Dilivery based on how far the buyer from kl, if to much far (outside Klang Valley and sermaban) I can't deliver. Thanks
