Hi Friends I am Venkatesh M I am Back I am doing interesting and useful project called Smart Bin.

Materials Required:

4 Cardboard Boxes
Double side Tape
9v Battery
Some Thread
Servo Motor
Ultra Sonic Sensor
Battery Connector
Some Jumping Wires
Arduino
Scissors
Big Transparent Tape
Nut

Step 1: Joining

Step 1:

Cut the four Card board boxes in 6 equal parts.

Using Big Transparent Tape make like a cuboid by joining the 6 cardboard sheet.

As shown in the figure.

Step 2: Opening and Closing

Step 2:

After making like a box take the first portion (top cardboard box) cut it into 2 parts.

After cut Stick it using tape.

Make it such that it can open and close.

Then stick Servo Motor on the top portion using Glue Gun.

After take nut tie thread to the nut and take the other portion of the thread and tie that one to the first hole of the Servo Motor.

Step 3: Coding

Step 3:

Insert Code as given below:

#include //servo library
Servo servo; int trigPin = 5; int echoPin = 6; int servoPin = 7; int led= 10; long duration, dist, average; long aver[3]; //array for average

void setup() { Serial.begin(9600); servo.attach(servoPin); pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT); servo.write(0); //close cap on power on delay(100); servo.detach(); }

void measure() { digitalWrite(10,HIGH); digitalWrite(trigPin, LOW); delayMicroseconds(5); digitalWrite(trigPin, HIGH); delayMicroseconds(15); digitalWrite(trigPin, LOW); pinMode(echoPin, INPUT); duration = pulseIn(echoPin, HIGH); dist = (duration/2) / 29.1; //obtain distance } void loop() { for (int i=0;i<=2;i++) { //average distance measure(); aver[i]=dist; delay(10); //delay between measurements } dist=(aver[0]+aver[1]+aver[2])/3;

if ( dist<50 ) { //Change distance as per your need servo.attach(servoPin); delay(1); servo.write(0); delay(3000); servo.write(150); delay(1000); servo.detach(); } Serial.print(dist); }
