Smart Shopping Trolley with RFID, Line Following & Auto Billing

Welcome to our latest project – a Smart Shopping Trolley that makes shopping more convenient using RFID technology! Project Overview: This smart trolley allows users to scan items using RFID tags, which are then displayed on an LCD screen along with their price. If needed, users can remove an item from the cart by pressing the reset switch on the dashboard. At the end of shopping, scanning a total RFID card calculates the final bill, displaying it on the LCD and automatically sending an invoice via email. Chapters: 00:00 Introduction 00:22 What's inside 00:50 Let's start shopping 02:47 Glimpse of making Features & Components Used ✅ RFID Scanning – Each item is tagged with an RFID chip, allowing seamless scanning and automatic billing. ✅ Item Removal Feature – Users can remove an item by pressing the reset switch on the trolley’s dashboard. ✅ LCD Display – Shows scanned item names, prices, and total bill. ✅ Line-Following Navigation – The trolley follows a predefined path using IR sensors and DC geared motors. ✅ Obstacle Avoidance – Equipped with an ultrasonic sensor to prevent collisions. ✅ Wireless Connectivity – The NodeMCU module enables internet connectivity to send the invoice. ✅ Microcontrollers – Powered by Arduino Mega and NodeMCU for smooth operation. How It Works 1️⃣ Scan items using RFID – Place items in the trolley, and they will be added to the bill automatically. 2️⃣ LCD Display Updates – Item name and price appear instantly. 3️⃣ Remove Items Easily – Press the reset switch to remove an item from the cart. 4️⃣ Line-Following Navigation – The trolley moves automatically along the shopping path. 5️⃣ Total Bill Calculation – Scan the final RFID card to see the total amount. 6️⃣ Invoice Sent to Email – The system sends a digital receipt directly to the user’s email.
