The Arduino Ethernet Shield allows an Arduino board to connect to the internet. It is based on the Wiznet W5100 ethernet chip (datasheet).
These posting will introduce and examine the use of Ethernet networking with Arduino systems.
The project presented here it is a TCP/IP socket system between an Arduino Ethernet Shield and a program running in a laptop elaborated by Processing. To demonstrate a total communication between the client and the server of the TCP/IP socket, I’ve designed a program in which the data sensors are represented in the screen and when a button is pushed, the client or the server respond with a light.
To test the performance of the W5100 shield, you need to know a real-time data brokerage platform - DeviceBit platform. Upload the data collected by sensors to DeviceBit through the W5100, and you can then DIY a mini smart home system.
This IoT project explores how to connect Arduino to Ubidots and Android. One important aspect in Arduino Internet of things programmin is how to connect arduino to internet and store date to IoT cloud platforms using arduino ethernet shield. This aspect is important because it is possible to store data in the cloud and then analyze it. Once the data, like sensor values, is on the cloud is possible to access it using smart phones and control remotely the Arduino board.
This example will help makers who want to make IoT device for Home Automation or Building Automation.
This posting shows how to use API of OpenWeatherMap site that provides weather information using WizArduino MEGA WiFi.
This article is an example of how to store and manage sensor data by using the Cloud service. he Cloud service that I'd like to introduce is Dweet.io.
