How It Works

This project integrates software automation with physical hardware by running a Python script on a Raspberry Pi 5 that interfaces with WhatsApp and local General-Purpose Input/Output (GPIO) pins. During the initial setup using a monitor, keyboard, and mouse, the Raspberry Pi is connected to the internet and configured with necessary Python libraries including RPi.GPIO, OpenCV, PyAutoGUI, and Pyperclip. A standard web browser on the Raspberry Pi logs into WhatsApp Web, allowing the Python script to monitor incoming chat messages. Using PyAutoGUI and Pyperclip, the automation script reads incoming text commands from a designated chat interface. When a specific command is received, the script processes the string and triggers the RPi.GPIO library to alter the electrical state of a specific GPIO pin connected to an external LED via jumper wires. By driving the GPIO pin HIGH or LOW, the circuit completes or breaks, turning the LED on or off respectively. This loop of reading web messages and toggling hardware states creates a functional messaging bridge to physical home automation without requiring paid commercial API subscriptions.

Why Build This

Develop practical software-hardware integration skills by linking web automation scripts directly to physical microcontroller input/output pins.

Implement cost-effective Internet of Things (IoT) control loops using accessible tools like Python and desktop automation libraries instead of expensive proprietary APIs.

Gain undergraduate-level experience in setting up headless or peripheral-driven Linux environments for remote home automation prototyping.

Real-World Application

Remote home appliance control, automated customer support messaging, and DIY smart-home notifications using popular messaging platforms without paid APIs.

Frequently Asked Questions

Do I need a paid WhatsApp Business API to make this bot work?

No, this project uses Python GUI automation libraries like PyAutoGUI to interact directly with WhatsApp Web in a browser, bypassing the need for paid API keys.

Can I control real household appliances instead of just an LED?

Yes, by replacing the LED and jumper wire setup with a properly isolated relay module connected to the GPIO pins, you can control high-voltage AC appliances safely.

Why are a monitor, keyboard, and mouse required if it's an automation project?

They are needed during the initial setup to connect to the internet, install software packages, and authenticate your session on WhatsApp Web.
