Sniffer

Raspberry Pi GPIO Button and LED Control

This Python script utilizes the RPi.GPIO library to control an LED using a button press on a Raspberry Pi. The script sends UDP messages to control the state of an LED connected to another device on the network.

Requirements

• Raspberry Pi with GPIO support
• Python 3
• RPi.GPIO library

Setup

1. Connect a button to GPIO pin 21 on your Raspberry Pi.
2. Make sure the RPi.GPIO library is installed on your Raspberry Pi.

   pip install RPi.GPIO

Usage

Run the script on your Raspberry Pi:

python Sniffer.py

Press the button connected to GPIO pin 21. The script alternates between turning the LED on and off, sending UDP messages to the specified IP and port.

UDP Messages

The script sends UDP messages to control the state of the LED on another device. The messages are defined as follows:

• UDP_MESSAGE_LED_ON: Message to turn the LED on.
• UDP_MESSAGE_LED_OFF: Message to turn the LED off.

Note

• The script assumes an LED control protocol based on UDP messages. Make sure the receiving device is configured to interpret these messages correctly.
