Arduino based Smart Trash Can B24

✨ Introduction

In this project, I have created a smart trash bin based on Arduino. Why did I choose to create such a project? Because as we know, trash bins are among the dirtiest objects, especially their lids. This often discourages people from opening the bin, leading them to litter improperly.

⚙️ Required components:

1. Arduino UNO

2. Motor Servo (Tower Pro SG90)

3. Obstacle Avoidance Sensor Module

4. USB B wire (USB Printer)

5. Jumper wire (Male-Male)

6. Jumper wire (Male-Female)

7. Pin Header Male

8. Trash bin

🖥️ Software used:

• Arduino IDE

👷🏻‍♂️ Installation steps:

1. Connection from the Obstacle Sensor to Arduino UNO:

• OUT → Digital Pin 2
• GND → GND
• VCC → 5V
• Connect using Male-Female Jumper Cables or Male Pin Headers.

2. Connection from the Servo Motor to Arduino UNO:

• Brown wire → GND
• Red (middle) → 5V
• Yellow/orange → Digital Pin 8
• Connect using Male-Male Jumper Cables or through the built-in adapter on Arduino.

3. After connecting the Arduino UNO, Servo Motor, and Obstacle Sensor with jumper cables and/or pin headers, the next step is to assemble them onto the prepared trash bin.

4. Next, upload the program code to the Arduino by connecting the Arduino to your PC/Laptop using a USB Printer cable.

5. Open the Arduino IDE on your PC/Laptop. If you haven't downloaded the Arduino IDE yet, you can download it from Official website and choose the appropriate version for your operating system (Windows/Linux/MacOS).

6. Open the Arduino IDE, go to Select Board > Select other board and port... > Scroll down and choose Arduino UNO > click "OK".

7. Copy and paste the following code:

#include <Servo.h>
Servo myservo;
int angle =0;
int angleStep =50;

void setup() { 
  myservo.attach(8);
  pinMode(2,INPUT_PULLUP);
}

void loop() {
  if (digitalRead(2) == HIGH){
myservo.write(180);
  }
  else {
  myservo.write(-180);
  }
}

8. Click on the "➔" (Upload) button in the Arduino IDE.

9. Disconnect the USB Printer cable from your computer/laptop and replace it with a regular phone charger head, then plug it into a power outlet. Test the system by approaching your hand or an object near the Obstacle Sensor. You're done!

🌟 This sequence of steps guides you through assembling the components, programming the Arduino, and testing your smart trash bin project.
