Smart Restaurant Menu Ordering System using Arduino

The Smart Restaurant Menu Ordering System operates using a dual-microcontroller setup powered by two Arduino Uno boards communicating wirelessly. At the customer table, the first Arduino Uno acts as the input terminal. It is equipped with a 2.4-inch TFT LCD Touch shield that displays the digital menu options. When a user interacts with the touch screen to select their food items, the Arduino processes these touch inputs and packages the order data. This data is then sent out over the air using a 433MHz RF Transmitter module. On the kitchen side, a 433MHz RF Receiver module captures the transmitted radio signals and passes them to the second Arduino Uno. This receiving Arduino decodes the order information and updates a secondary display, a 16*2 LCD Module connected via an I2C module, which presents the kitchen staff with the incoming order details. Simultaneously, a buzzer sounds to alert the kitchen personnel that a new order has arrived, ensuring prompt preparation and reducing miscommunication between customers and staff.

Modern restaurant automation systems to streamline ordering processes, reduce wait times, and improve communication between tables and kitchen staff.
