Smart Dustbin using Arduino

Today I am going to describe how to make a Smart dustbin using Arduino UNO ( with Arduino code & video tutorial)

working principle

when your hand is near ultrasonic sensor then the servo motor rotates for 90 degrees & pull the dustbin’s cardboard cover & after few seconds servo rotates to 0 degrees & the dustbin become closed.

You need to make :

1. Arduino Uno
2. Ultrasonic Sensor HC-SR04
3. 9G Servo Motor
4. Cardboard
5. Jumper wire
6. A plastic Dustbin
7. 9 Volt battery or power bank
8. Arduino Code

The complete making process is in this video

Connections :

• Connect HC-SR04 Trig pin to Arduino D5 pin
• Connect HC-SR04 Echo pin to Arduino D6 pin
• HC-SR04 VCC to Arduino 5 volt
• HC -SR04 GND to Arduino GND

• Connect Servo motor signal pin to Arduino D7 pin
• Servo motor VCC to Arduino 3.3 volt pin
• Servo motor Gnd to Arduino gnd pin

• For the power supply, you can use 9Volt battery or power bank

For upload Code to Arduino Uno Please install & open Arduino IDE software

Select board Arduino UNO, select com port where Arduino is connected

creat a .ino new file & save it then delete all existing from new .ino file & Download the code txt file from here, copy all from downloaded, txt file & past it in new .ino file.

Upload the code to Arduino
