A smart trashcan is a perfect solution to create a more efficient waste management system. With the help of Arduino, it is now possible to convert a regular trashcan into a smart one that can automatically sort and manage waste. In this blog post, we will discuss how you can make a smart trashcan using Arduino.

Materials Required:

1. Arduino Uno or similar microcontroller
2. HC-SR04 Ultrasonic Distance Sensor
3. Servo Motor
4. LED Lights
5. Jumper wires
6. Breadboard
7. 9V Battery or USB cable for power supply
8. A trashcan

Step 1: Building the Circuit

The first step is to build the circuit for our smart trashcan. Connect the HC-SR04 sensor to the Arduino board using jumper wires. The VCC pin of the sensor should be connected to the 5V pin on the Arduino, the GND pin to GND, the TRIG pin to digital pin 9 and the ECHO pin to digital pin 10.

Next, connect the servo motor to the breadboard and connect the power and ground pins to the 5V and GND pins on the Arduino board. Connect the signal pin of the servo motor to digital pin 8.

Finally, connect the LEDs to the breadboard and connect the power and ground pins to the 5V and GND pins on the Arduino board. Connect the signal pin of the LEDs to digital pin 7.

Step 2: Programming the Arduino

After setting up the circuit, it’s time to program the Arduino. You can use the Arduino IDE to write and upload the code to your board. The code for this project is available on GitHub and can be easily modified according to your needs.

The basic working of this code is as follows: The ultrasonic sensor continuously measures the distance of the trash can lid from the ground. When it detects an object, the Arduino reads the distance and opens the lid using the servo motor. Once the object is dropped inside the trashcan, the lid closes automatically. At the same time, the LED lights turn on to indicate that the trashcan is in use.

Step 3: Making the Trashcan Lid

To make the trashcan lid, you can use cardboard or any other material of your choice. Cut a rectangular piece of cardboard and attach it to the servo motor using glue or tape. Make sure that the lid can open and close smoothly.

Step 4: Testing and Final Touches

Before using the smart trashcan, make sure to test the system by dropping waste in front of the sensor. If everything is working correctly, place the lid on your trashcan and secure it with tape or glue.

Lastly, you can add some finishing touches to your trashcan, such as painting it or adding a design to make it more appealing.

In conclusion, with the help of Arduino and a few simple materials, you can easily transform a regular trashcan into a smart one. This project not only helps in efficient waste management but also promotes the use of technology for a greener environment.
