Abstract:

          The main aim of our project is to develop an automated dustbin. Dustbins (or Garbage bins, Trash Cans) are small plastic (or metal) containers that are used to store trash (or waste) on a temporary basis. They are often used in homes, offices, streets, parks etc. to collect the waste. In some places, littering is a serious offence and hence Public Waste Containers are the only way to dispose small waste .Usually, it is a common practice to use separate bins for collecting wet or dry, recyclable or non-recyclable waste .In this project, we have designed a simple system called Smart Dustbin using Arduino, Ultrasonic Sensor and Servo Motor, where the lid of the dustbin will automatically open itself upon detection of human hand.

       So, we placed an ultrasonic sensor over a dustbin, which will predict the distance of the object or particles.

ULTRASONIC SENSOR :  

In Automated smart dustbin Arduino works, when object come in front of the dustbin it will open automatically with the help of a servo motor. And to open the lid of the dustbin, servo is placed near the hinge where the lid is connected to the main Container.  

Working:

Step 1: Make two holes to the Ultrasonic Sensor near the lid  of the dustbin.

Step 2: Now, from the inside, place the Ultrasonic Sensor through the holes and fix its position with the help of glue and cello tape.

Step 3: After placing sensor, we move on to the servo and it is placed near the hinge where the lid is connected to the main container

Step 4: The final step in the build process is to make the necessary connections using long connecting wires as per the circuit diagram and securing these wires so that they don’t hang around.

Step 5: All the wires from both the components i.e. The Ultrasonic Sensor and Servo Motor are connected to respective pins of Arduino. This finishes up the build process of the Automated Smart Dustbin.

After setting up the Smart Dustbin and making all the necessary connections, upload the code to Arduino and provide 5V power supply to the circuit. Once the system is powered ON, Arduino keeps monitoring for any object near the Ultrasonic Sensor.  

If the Ultrasonic Sensor detects any object like a hand for example, Arduino calculates its distance and if it is less than a certain predefined value, Arduino will activate the Servo Motor and with the support of the extended arm, it will list the lid open.

After a certain time, the lid is automatically closed.
