Waste segregator using Arduino Uno r3

Hi guys I just want to ask, is it possible to make a automatic waste segregator using capacitive proximity sensor (PNP), ultrasonic sensor, servo motor 90g, and stepper motor 28BYJ-48?? if yes is it possible for you to share a code and a diagram,and if not why?do i need to add some material? :grin:btw the board that I'm using is Arduino Uno r3..,.. thanks in advance

You have to have some idea how to accomplish the determination of different kinds of waste. Which kinds of waste, how to detect differences?

You must apply some machine learning algorithms. Without that, the system cannot differentiate between types of waste materials. You can use Neuton TinyML and Arduino mega. For example, here is a food quality inspector. You can use the same technique for waste segregation: Real-time Food Quality Prediction - Share Project - PCBWay

Magnets separate ferrous material.
Air separates light material from dense.
Holes separate large objects from small.
Light shines through transparent/translucent material.
Use combinations to further refine separation.

Plastic bottles, plastic wrap, and paper are the materials that I'm thinking to segregate. I'm thinking to use the capacitive proximity sensor, humidity and temperature sensor module,and ultrasonic sensor but I don't know if how to use the capacitive proximity sensor and the code :sweat_smile::sweat_smile:

This is my code
*/
#include <Stepper.h>

const int proximitySensorPin = 2;
const int humidityTempSensorPin = A0;
const int trigPin = 9;
const int echoPin = 10;

const int stepsPerRevolution = 200; // Change according to your stepper motor

Stepper stepper(stepsPerRevolution, 8, 9, 10, 11); // Adjust pins based on your connections

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

// Set up stepper motor
stepper.setSpeed(100); // Adjust stepper motor speed as needed
}

bool detectPlasticBottles() {
return digitalRead(proximitySensorPin) == HIGH;
}

bool detectPlasticWrap() {
int humidityTempReading = analogRead(humidityTempSensorPin);
return humidityTempReading > 500;
}

bool detectPaper() {
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
long duration = pulseIn(echoPin, HIGH);
float distance = duration * 0.034 / 2;
return distance < 10;
}

void rotateStepper(int degrees) {
int steps = (degrees * stepsPerRevolution) / 360;
stepper.step(steps);
delay(500); // Adjust delay based on your motor's speed and requirements
}

void loop() {
if (detectPlasticBottles()) {
Serial.println("Plastic Bottles detected. Segregate as plastic.");
rotateStepper(60); // Rotate 60 degrees for plastic bottles
} else if (detectPlasticWrap()) {
Serial.println("Plastic Wrap detected. Segregate as plastic.");
rotateStepper(120); // Rotate 120 degrees for plastic wrap
} else if (detectPaper()) {
Serial.println("Paper detected. Segregate as paper.");
rotateStepper(180); // Rotate 180 degrees for paper
} else {
Serial.println("Unknown waste. Further analysis needed.");
}

delay(1000);
}

Sample code should be available for all your sensors. Then find out how the sensors react on different kinds of waste and adjust your code for best operation.

Short answer: No way.
