Turn a Dustbin Into a Smart Dustbin With LinkitONE

Want to make a cool science project? Want your dustbin to open automatically when you are near to it so you can throw items easily? Then you are at the right place!

Here I’ll show you how to make a basic dustbin that automatically opens up when any kind of motion is detected.

1 . LinkitONE board

2. Servo motor

3. Breadboard

5. PIR motion sensor

6. Battery pack

Look into the dustbin and see that where can you fix a motor that opens the head of the dustbin. I found a foot-opener and I’ll attach the servo motor there.

Now assemble your servo motor as shown in the images.

Carefully do it so it is permanently tight enough.

Now attach a servo motor to the foot-opener of the dustbin using a servo motor. When the servo motor will rotate, the dustbin will automatically open its cap.

Now attach the PIR motion sensor to the dustbin just as shown in the image.

Pin connections: PIR to LinkitONE

VCC – 5V

DATA – D8

GND – GND

After this we’ll write some code for the sensor that activates the motor when motion is detected!

The code is really simple here!

We just need to read the motion sensor, if the motion is detected, the servo motor will start.

CODE:

---------------------

#include

Servo myservo;

void setup() {

myservo.attach(9);

pinMode(8, INPUT);

myservo.write(90);

}

void loop() {

if(digitalRead(8) == 1)

{

myservo.write(90);

}

else

{

myservo.write(0);

}

delay(250);

}

-------------------

Now attach the board to the dustbin tightly and finalize the project!

Check for all the connections that they are correct.

Once done, you are ready for testing!

Take a balled-paper near dustbin and see it open up automatically!

Congrats! you've made your own smart dustbin!
