Wireless Restaurant Waiter Calling System Using Arduino and HC-12 RF Modules

Q-call (2).jpg

A practical and easy-to-build wireless waiter calling system designed for restaurants, cafés, hotels, clinics, and service centers. This project uses Arduino and RF wireless communication to allow customers to call waiters directly from their table using dedicated transmitter units.

Supplies

Main Components

  1. Arduino UNO
  2. HC-12 RF module
  3. 2 Push buttons
  4. 2 × 10kΩ resistors
  5. Jumper wires
  6. 5V power supply
  7. 2 LEDs
  8. 2 × 220Ω resistors
  9. Buzzer/Speaker
  10. 100Ω resistor
  11. Breadboard

This project is a wireless RF communication system using Arduino and HC-12 modules. It allows wireless transmission of ON/OFF commands between transmitter and receiver units and can be used for automation, wireless alerts, and control systems.

How It Works

When the ON button is pressed, the transmitter sends a wireless serial command through the HC-12 module. The receiver processes the command and activates the corresponding LED and buzzer. Download complete files, code, schematic, and documentation. https://netontheright.gumroad.com/l/qsrpz
