Arduino Sonar System with C Lang TCP Server

Overview

This project implements a server that receives data from an Arduino-based sonar system, logging the distance and angle of detected objects. The system is designed to monitor the environment and record the presence of foreign entities.

Features

• Real-time Monitoring: The server receives real-time data from the sonar system.
• Data Logging: Captures and logs distance and angle information to distance_log.txt.
• Client-Server Architecture: Uses TCP/IP to establish a connection between the server and the Arduino client.

Installation

To set up the project locally, follow these steps:

1. Clone the repository:

   git clone https://github.com/SPC-Toad/sonar-tcp-server.git

2. Navigate to the project directory:

   cd sonar-tcp-server

Usage

1. Set Your IP Address:

   • Ensure you use your current device’s IP address, not the loopback address (localhost / 127.0.0.1).
   • To find your IP address:
     • Windows:

       ipconfig

     • Linux:

       ifconfig

   • Typically, it will be in the format 192.168.xx.xx.

2. Configure Network Details:

   • In server.c, update line 48 with your IP address. When starting the server, provide a port number.
   • In sonar.ino, fill in the following:
     • Your Wi-Fi SSID
     • Your Wi-Fi password
     • The IP address and port number (must match the server configuration).

3. Compile and Run the Server:

   • Use the provided Makefile to compile and manage the server:

     // Compile the server
     make server
     // Start the server on port 7777 (or any other port)
     ./server 7777
     // Clean up compiled files
     make clean

Make sure the Arduino sonar system is correctly set up and ready to connect to the server.

How It Works

The server runs on a specified IP address and port, listening for incoming connections from the Arduino sonar client.

1. Server Initialization: The server is set up to listen on the specified IP address and port.
2. Client Connection: The Arduino sonar acts as a client, establishing a connection with the server.
3. Data Transmission: Once connected, the sonar takes readings of the surrounding environment, including the distance and the degree of detection.
4. Data Logging: The server receives this data and records it into the distance_log.txt file, capturing both the distance and the angle at which the object was detected.

Logs

The distance_log.txt file contains entries in the following format:

[YYYY-MM-DD HH:MM:SS] Distance @Degree°

For example:

[2024-08-21 18:06:51] 16.33 @42°
[2024-08-21 18:06:51] 36.53 @44°

These logs help you track the detected objects' distance and angle over time.

Test Run

Here’s an example run. Please note this is my first video recorded on my phone, and I'm on a budget crunch!
