How to make Smart 🤩Dustbin✌️
#arduinoprojects #engineeringprojects #shorts

Creating a smart dustbin with an Arduino, ultrasonic sensor, and servo motor involves integrating these components to automate the lid of the dustbin. Here are the steps to make one:

Materials Needed:

Arduino board (e.g., Arduino Uno)
Ultrasonic sensor (e.g., HC-SR04)
Servo motor
Dustbin with a lid
Jumper wires
Power source (e.g., battery or USB)

Steps:

Prepare the Dustbin:

Ensure that your dustbin has a lid or a cover that can be controlled by a servo motor.
Mount the Ultrasonic Sensor:

Attach the ultrasonic sensor to the top of the dustbin, facing upward. This sensor will detect when someone approaches the dustbin.
Wire the Components:

Connect the ultrasonic sensor to the Arduino using jumper wires. Typically, you'll need to connect the sensor's VCC and GND pins to the Arduino's 5V and GND pins, and the Echo and Trig pins to any available digital pins.

Connect the Servo Motor:

Connect the servo motor to the Arduino. Usually, the servo has three wires: power (red), ground (brown), and signal (orange). Connect the power and ground wires to the 5V and GND pins on the Arduino, and the signal wire to a digital pin.
Write the Arduino Code:

Write an Arduino sketch (code) that reads the distance measured by the ultrasonic sensor and controls the servo motor accordingly. You can use the Arduino Servo library for servo control and the Ultrasonic library for the sensor. Here's a simplified example:

code here :

Servo myservo;
Ultrasonic ultrasonic(TrigPin, EchoPin);

void setup() {
}

void loop() {
if (distance lessthen 20) { // Adjust this threshold as needed
delay(2000); // Keep it open for 2 seconds
}
// Add additional logic as needed
}

Test and Adjust:

Upload the code to your Arduino board and test the system. The servo should open the lid when someone approaches within the specified distance (e.g., 20 cm in the example). You can adjust the distance threshold and timing as needed.
Power Supply:

Ensure your setup has a stable power supply. Depending on the servo and ultrasonic sensor you're using, you may need an external power source.
