The smart dustbin is a modern solution designed to streamline waste management processes by integrating Arduino technology. Equipped with sensors, the dustbin detects the presence and volume of trash, automatically opening its lid when approached by the user. Arduino serves as the control hub, processing sensor data and managing the bin's functions. Additionally, the smart dustbin can be programmed to send alerts when it's nearing capacity, facilitating timely waste disposal and maintenance. With its efficient and automated operation, the smart dustbin enhances convenience, promotes cleanliness, and contributes to a more sustainable environment.

// constants won't change
const int TRIG_PIN = 6;
const int ECHO_PIN = 7;
const int SERVO_PIN = 9; // Arduino pin connected to Servo Motor's pin
const int DISTANCE_THRESHOLD = 11; // centimeters
Servo servo; // create servo object to control a servo
// variables will change:
float duration_us, distance_cm;
void setup() {Serial.begin (9600); // initialize serial port
pinMode(TRIG_PIN, OUTPUT); // set arduino pin to output mode
servo.attach(SERVO_PIN);
servo.write(0);
}
void loop() {// generate 10-microsecond pulse to TRIG pin
digitalWrite(TRIG_PIN, HIGH);
delayMicroseconds(10);
digitalWrite(TRIG_PIN, LOW);
// measure duration of pulse from ECHO pin
duration_us = pulseIn(ECHO_PIN, HIGH);
// calculate the distance
distance_cm = 0.017 * duration_us;
if(distance_cm < DISTANCE_THRESHOLD)
servo.write(90); // rotate servo motor to 90 degree
else
servo.write(0); // rotate servo motor to 0 degree
// print the value to Serial Monitor
Serial.print("distance: ");Serial.print(distance_cm);
Serial.println(" cm");delay(2000);
