Restaurant Menu Ordering System Using Arduino Mega and 3.9-Inch TFT Touch Screen

Introduction

The Restaurant Menu Ordering System is an advanced touchscreen-based ordering system that replaces traditional paper menus with a digital touch interface. Built using Arduino Mega and a 3.9-inch TFT touch screen, this system allows customers to browse the menu, select items, and place orders directly from their table, streamlining the restaurant’s service and reducing manual workload.

Components Used

• Arduino Mega – The central controller for processing user inputs and handling menu selections.
• 3.9-inch TFT Touch Screen – Displays the menu interface and allows touch-based item selection.
• Wi-Fi Module (ESP8266/NodeMCU) – Sends order data wirelessly to the kitchen or main server.
• Buzzer & LED Indicators – Provide audio and visual confirmation of orders.
• Micro SD Card Module – Stores menu images and price data.
• Thermal Printer (Optional) – Prints receipts for customer confirmation.

How It Works

1. Touchscreen Menu Navigation – The 3.9-inch TFT display shows a digital menu with food categories and images.
2. Item Selection – Customers tap on their preferred food items, selecting quantity and adding them to the cart.
3. Order Confirmation – The total bill is displayed, and customers can confirm their order with a touch button.
4. Order Transmission – Using Wi-Fi or Bluetooth, the order details are sent to the kitchen display system.
5. Receipt Generation (Optional) – A thermal printer can print an order receipt for verification.
