Introduction
In this article, we will be looking at how to make a smart dustbin using Arduino, an ultrasonic sensor, and an SG-90 servo motor. Let's start!
Hardware Required
We will need the following components for making the Arduino smart dustbin:
If you don't have any of the hardware then you can click on the required component name and buy it from our store and successfully complete this smart dustbin project.

1. Arduino Uno
Ardunio Uno is a development board that manages all of the processing for smart dustbin projects.
2. Ultrasonic Sensor HC-SR-04
This sensor functions as an object detecting sensor. It measures the object's distance from the sensor.
3. SG-90 Servo
A Servo motor is used for moving the dust bin lid.
4. Jumper Wires
Used to do circuit connections between different components.

Working Principle
Smart dustbin works on the principle of object detection using an ultrasonic sensor. The ultrasonic sensor transmits sound waves.
These waves get reflected whenever an object comes into the vicinity of the sensor. This generates an electrical signal which is used to open the dustbin lid.

SMART DUSTBIN ARDUINO CODE
Lid of the dustbin gets opened when a person comes in range of 30cm in front of the dustbin

#include //INCLUDES SERVO LIBRARY
Servo servo;
int trigPin = 5;
int echoPin = 6;
int servoPin = 9;
long duration, distance, average;
long averDist[3];
void setup() {
Serial.begin(9600);
servo.attach(servoPin);
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
servo.write(0); //CLOSES CAP ON STARTING
delay(100);
servo.detach();
}
void measure() {
digitalWrite(trigPin, LOW);
delayMicroseconds(5);
digitalWrite(trigPin, HIGH);
delayMicroseconds(15);
digitalWrite(trigPin, LOW);
pinMode(echoPin, INPUT);
duration = pulseIn(echoPin, HIGH);
distance = (duration / 2) / 29.1; //CALCULATES DISTANCE
}
void loop() {
Serial.println(distance);
for (int i = 0; i <= 2; i++) { //CALCULATES AVERAGE DISTANCE
measure();
averDist[i] = distance;
delay(10);
}
distance = (averDist[0] + averDist[1] + averDist[2]) / 3;
if ( distance <= 30 ) {
servo.attach(servoPin);
delay(1);
servo.write(180);
delay(3500);
}
else
servo.write(0);
delay(1500);
servo.detach();
}
Servo motor;
This creates a servo object.

int trigPin = 5; |
The above lines assign trigger and echo pins of the ultrasonic sensor to 5 and 6 respectively. Servo’s PWM pin is connected to pin 9 of Arduino.
long duration, distance, average;
long averDist[3];
These are the variables created for storing and processing data from ultrasonic sensor.
|
servo.attach(servoPin); |
servo. Attach (servoPin) - attaches the servo variable which we created initially to the servo pin, set trigger and echo pins as Output and Input respectively, close the lid of the dustbin by setting servo to 0 positions, and then detach the servo object.
|
Serial.println(distance); |
Measure function calculates the distance and average calculates the average of 3 distances measured by ultrasonic sensor.
|
if ( distance <= 30 ) { |
If the distance is less than 30 then the dustbin lid is opened by setting the servo to 180 position otherwise the dustbin’s lid is closed.
