NetAnalyzer is an arduino based system that allows analyzing and detecting lan networks. Its operation is simple, connecting it to an Ethernet network links via DHCP and then allows to view network data (IP, Netmask, Gateway and DNS).
The functions to perform analysis on the network are: Ping a Gateway, Ping a DNS, Ping a Google DNS and Send Data by Email, among others. are not yet activated, as they are in development.

Step 2: Hardware

This project was modified on the fly and was created using a lot of recycling material, I do not have a complete list of materials and it took me a few days to create the diagram of the electronic circuit of it, I hope to be able to update this publication with more data.

Este proyecto se fue modificando sobre la marcha y se creo usando mucho material de reciclaje, no tengo una lista completa de materiales y me tomo unos días crear el diagrama del circuito electrónico del mismo, espero poder ir actualizando esta publicación con mas datos.

Step 3: Code and Libraries

This is one of the most important parts that, to avoid problems I divided the code into parts: LCD, Inputs (Buttons, Selector), Outputs (Led, Speaker) and Ethernet, I debugged each part and didn't have many problems to unite everything in a single project, maybe in some future version I will use an ESP8266 that already has more hardware power.
This project uses 2 libraries "LiquidCrystal" for the lcd screen, which is already included with arduino ide and "EtherCard" for the ethernet module, this last one has to be downloaded from its web since it is not included in arduino ide. To download just log on to the git repository of the library at, then press the green button with the text "Clone or Download" and finally open the link with the text "Download ZIP", you will start downloading from the ZIP file. Once you have finished downloading, locating and unpacking the ZIP file, this generates a folder, rename it to "EtherCard" and move the folder of arduino ide libraries, it is located inside the folder where the arduino ide projects are saved. If you were able to complete all the steps you already have the libraries for the project. We're going to schedule, just download the compressed file and extract it, this creates a folder "NetAnalyzer" with a file "NetAnalyzer. ino" inside it, you have to move this folder (with the file) to the location where you save Arduino IDE projects. then start Arduino IDE, configure board, port and open the NetAnalyzer project, just program the Arduino and you will be able to use the system.

Esta es una de las partes que mas importantes, para evitar problemas dividí el código en partes: LCD, Entradas (Botones, Selector), Salidas (Led, Parlante) y Ethernet, fui depurando cada parte y no tuve muchos problemas para unir todo en un solo proyecto , quizás en alguna futura versión use un ESP8266 que ya tiene mas poder de hardware. Este proyecto utiliza 2 librerías "LiquidCrystal" para la pantalla lcd, que ya se incluye con arduino ide y "EtherCard" para el modulo ethernet, esta ultima hay que descargar la desde su web ya que no esta incluida en arduino ide. Para descargar solo hay que ingresar al repositorio git de la librería en, luego presionar el botón verde con el texto "Clone or Download" y finalmente abrir el link con el texto "Download ZIP", se iniciara la descargar del archivo ZIP. Ya finalizada la descarga, localizar y descomprimir el archivo ZIP, esto genera una carpeta,m renombrar la a "EtherCard" y mover la carpeta de librerías de arduino ide, se encuentra dentro de la carpeta donde se guardan los proyectos de arduino ide. Si pudo completar todos los pasos ya tiene las librerías para el proyecto. Vamos a Programar, solo tienen que descargar el archivo comprimido y extraer lo, esto crea una carpeta "NetAnalyzer" con un archivo "NetAnalyzer.ino" en su interior, tienen que mover esta carpeta (con el archivo) a la ubicación donde guardan los proyectos de Arduino IDE. luego iniciar Arduino IDE, configurar placa, puerto y abrir el proyecto NetAnalyzer, solo resta programar el Arduino y ya podrán utilizar el sistema.

    So this is a "net analyser" that does not actually analyse nets. It is based on an arduino chip which really isn't big enough or fast enough so you might use an esp8266 soon. And ,the instructable does not contain much just yet but you will add to it.

    Hi, this project is already evolving to another one with esp8266 that is more powerful and with wireless support, besides that it will have bluetooth and thus be able to interact from a smartphone, table and/or computer. I will soon be uploading more info and probably create another instructable one with the new system. greetings.
