   • Then, go to Tools > Port and choose the port where your Arduino is connected.

Your Arduino IDE is ready to start Arduino programming. Also, setting up the Arduino IDE brings you closer to creating your smart dustbin project.

Writing the Code

The success of this project using Arduino Uno depends on creating an efficient and functional program. To begin with, let’s take a look at a clear breakdown of the code you’ll need.

• Code Structure: The program for your smart dustbin project using Arduino consists of:
  • Initializing the ultrasonic sensor to detect objects.
  • Controlling the SG90 servo motor to open and close the dustbin lid.
  • Combining these functionalities for seamless operation.
• Ultrasonic Sensor Readings: The ultrasonic sensor measures the distance between the dustbin and any approaching object. Use the following ultrasonic sensor Arduino code snippet to initialize and read values:

const int trigPin = 9; // Trigger pin of ultrasonic sensor
const int echoPin = 10; // Echo pin of ultrasonic sensor
long duration;
int distance;

void setup() {
    pinMode(trigPin, OUTPUT);
    pinMode(echoPin, INPUT);
    Serial.begin(9600);
}

void loop() {
    digitalWrite(trigPin, LOW);
    delayMicroseconds(2);
    digitalWrite(trigPin, HIGH);
    delayMicroseconds(10);
    digitalWrite(trigPin, LOW);

    duration = pulseIn(echoPin, HIGH);
    distance = duration * 0.034 / 2;

    Serial.print("Distance: ");
    Serial.println(distance);
    delay(500);
}

• Servo Motor Control: Once the ultrasonic sensor detects an object within a certain range (e.g., 20 cm), the SG90 servo motor opens the dustbin lid. Here’s the Servo motor Arduino code to achieve that:

#include <Servo.h>

Servo servoMotor;

void setup() {
    servoMotor.attach(3); // Connect the servo motor to pin 3
    servoMotor.write(0); // Initial position of the lid (closed)
}

void loop() {
    if (distance < 20) {
        servoMotor.write(90); // Open the lid
        delay(3000); // Keep it open for 3 seconds
        servoMotor.write(0); // Close the lid
    }
}

• Combining Sensor Input with Servo Control: Merge the ultrasonic sensor and servo motor functionalities to create the final code:

#include <Servo.h>

const int trigPin = 9;
const int echoPin = 10;
long duration;
int distance;
Servo servoMotor;

void setup() {
    pinMode(trigPin, OUTPUT);
    pinMode(echoPin, INPUT);
    servoMotor.attach(3);
    servoMotor.write(0);
    Serial.begin(9600);
}

void loop() {
    digitalWrite(trigPin, LOW);
    delayMicroseconds(2);
    digitalWrite(trigPin, HIGH);
    delayMicroseconds(10);
    digitalWrite(trigPin, LOW);

    duration = pulseIn(echoPin, HIGH);
    distance = duration * 0.034 / 2;

    if (distance < 20) {
        servoMotor.write(90);
        delay(3000);
        servoMotor.write(0);
    }

    delay(500);
}

This code for a smart dustbin project using Arduino is simple yet effective. It also ensures the dustbin lid operates automatically based on proximity.

Final Verified Code for Smart Dustbin Using Arduino

The final code for the Smart Dustbin using Arduino combines everything into one simple program. Specifically, it uses the ultrasonic sensor to measure the distance automatically. Meanwhile, the servo motor opens and closes the dustbin lid. If something comes within 20 cm of the sensor, the lid opens for 3 seconds and then closes. This code is ready to use, so you don’t have to mix or match multiple parts. It’s all set for your smart dustbin project. Click on the button below to download the full smart dustbin project code.

Step by step, we explain everything clearly so that beginners and experienced users can follow along easily. Next, you’ll learn how to write the code and understand its logic. This will also help you apply it to projects using the Arduino Uno.

Ultrasonic Sensor Integration

The ultrasonic sensor is the key component that detects an object’s distance from the dustbin. Its readings allow the dustbin to determine when to open and close the lid.

Steps to Integrate the Ultrasonic Sensor:

1. Connect the Sensor:
   • The HC-SR04 ultrasonic sensor has four pins: VCC, GND, Trig, and Echo.
   • Connect VCC to the Arduino Uno’s 5V pin and GND to GND.
   • Attach the Trig pin to digital pin 9 and the Echo pin to digital pin 10 of the Arduino board.
2. Write the Code: Below is the code snippet to initialize the ultrasonic sensor and read the distance.

// Ultrasonic Sensor Pin Configuration
const int trigPin = 9; 
const int echoPin = 10;

// Variable for Distance Measurement
long duration;
int distance;

void setup() {
  pinMode(trigPin, OUTPUT); // Trig pin as output
  pinMode(echoPin, INPUT);  // Echo pin as input
  Serial.begin(9600);      // Initialize Serial Monitor
}

void loop() {
  // Send a 10-microsecond pulse to Trig pin
  digitalWrite(trigPin, LOW);
  delayMicroseconds(2);
  digitalWrite(trigPin, HIGH);
  delayMicroseconds(10);
  digitalWrite(trigPin, LOW);

  // Measure the response time from Echo pin
  duration = pulseIn(echoPin, HIGH);

  // Calculate distance in centimeters
  distance = duration * 0.034 / 2;

  // Print the distance to the Serial Monitor
  Serial.print("Distance: ");
  Serial.print(distance);
  Serial.println(" cm");
  delay(500);
}

Explanation of the code:

• The sensor sends an ultrasonic wave via the Trig pin.
• The Echo pin measures the time it takes for the wave to bounce back.
• The distance is calculated based on the speed of sound.

Servo Motor Control

The servo motor opens and closes the dustbin lid. We’ll use the SG90 servo motor for this project because it is lightweight, efficient, and perfect for a simple Arduino setup.

Steps to Control the Servo Motor:

1. Connect the Servo Motor:
   • Connect the SG90 servo motor’s power (red wire) to the Arduino’s 5V pin.
   • Connect the ground (black/brown wire) to GND.
   • Attach the control pin (orange wire) to digital pin 6 of the Arduino.
2. Write the Code: Below is the code snippet for controlling the servo motor.

#include <Servo.h> // Include the Servo library

Servo myServo;  // Create a Servo object

void setup() {
  myServo.attach(6); // Attach the servo to pin 6
}

void loop() {
  // Open the lid
  myServo.write(90); // Rotate the servo to 90 degrees
  delay(2000);       // Hold for 2 seconds

  // Close the lid
  myServo.write(0);  // Rotate the servo back to 0 degrees
  delay(2000);       // Hold for 2 seconds
}

Explanation of the code:

• The Servo library simplifies the control of servo motors.
• The write() function sets the angle of the servo and opens and closes the lid.

Combining Sensor Input with Servo Control

Let’s use Arduino and an ultrasonic sensor to measure distance. This also controls a servo motor for a touchless smart dustbin.

Steps:

1. Measure the distance using the ultrasonic sensor.
2. Open the lid if the distance exceeds a set threshold (e.g., 15 cm).
3. Close the lid after a few seconds.

#include <Servo.h> // Include the Servo library

// Pin Configurations
const int trigPin = 9;
const int echoPin = 10;

Servo myServo; // Create a Servo object

// Variables
long duration;
int distance;

void setup() {
  pinMode(trigPin, OUTPUT);
  pinMode(echoPin, INPUT);
  myServo.attach(6); // Attach the servo to pin 6
  myServo.write(0);  // Ensure lid is initially closed
  Serial.begin(9600); // Initialize Serial Monitor
}

void loop() {
  // Ultrasonic Sensor Logic
  digitalWrite(trigPin, LOW);
  delayMicroseconds(2);
  digitalWrite(trigPin, HIGH);
  delayMicroseconds(10);
  digitalWrite(trigPin, LOW);
  duration = pulseIn(echoPin, HIGH);
  distance = duration * 0.034 / 2;

  // Control Servo Based on Distance
  if (distance > 0 && distance <= 15) { // Object detected within 15 cm
    myServo.write(90); // Open the lid
    delay(2000);       // Wait for 2 seconds
  } else {
    myServo.write(0); // Close the lid
  }

  delay(500); // Small delay for stability
}

Explanation of the Code:

• The code combines the distance detection logic with the servo control.
• When an object is detected within 15 cm, the servo motor opens the lid.
• After a delay, the lid closes automatically.

Complete Code Listing

Below is the complete Arduino code for the smart dustbin project using Arduino:

#include <Servo.h>

// Pin Configurations
const int trigPin = 9;
const int echoPin = 10;

Servo myServo; // Create a Servo object

// Variables

    myServo.write(90); // Open the lid
    delay(2000);       // Wait for 2 seconds
  } else {
    myServo.write(0); // Close the lid
  }

  delay(500); // Small delay for stability
}

This complete code is fully functional and well-commented for easy understanding. Following these steps, you’ve successfully created a project using Arduino Uno, an innovative and practical solution for touchless waste management.
