Smart Shopping Cart Using RFID & Arduino

Smart Shopping Cart using Arduino

Introduction

In this Tutorial, we will build a Smart shopping cart with an EM-18 RFID Module And Arduino. This project is easy to build because it requires only a few components. our system is just scanners in the mart all products have their own RFID tag, when you just scan the product name and price will display on an LCD Display.

Here We used the Arduino nano controller and we showed the pin diagram of the Arduino nano microcontroller.

16×2 LCD Display

In this Project, we used the 16×2 LCD the team or the cost of the product that you purchase in a mart.

they are connected to the I2C protocol and are only four-pin connections.

  • VCC – 5V
  • GND – GND
  • SDA – A4
  • SCL – A5

Components1

If you did not use the I2C then You are required to connect a 4-pin connection I will provide all proper connections in this Article.

  • Rs – 12
  • Rw – GND
  • E – 11
  • D4 – 10
  • D5 – 9
  • D6 – 8
  • D7 – 7

PCB Design

  • we designed a PCB with the help of EasyEDA Software
  • and in this circuit diagram, we used the 16×2 LCD Display With I2C Module.

Demo Of Project

We just connected the USB cable to the Arduino nano microcontroller the LCD Will Display the Welcome Message.

Now we just scan the first item card and the LCD will display the item name and cost of the item.

Now we just scan the Second item card and the LCD will display the item name and cost of the item.

After a few seconds if we do not scan any card the LCD Will Display the total cost How many items do you purchase in a mart and how much cost you pay for the mart?
