This project analyze the work of the popular Ethernet-based W5100 shield controller. As a final example, which can be useful when building “smart homes”, to direct the four-channel relay module via a local network or the internet.
1. Arduino UNO
2. Ethernet Shield
3. 4 Channel Relay module
The role played by the client browser through which you connect to the server. The main purpose of the customer – is to send various requests to the server, such as a request to display some information(GET_ or request to transfer any data(POST). In the simplest case, you need not worry about their structure for you do all the browser.
Server is the actual ethernet Shield. It works in accordance with the HTTP protocol. The sketch must be specified ip address where you will receive access to it.
Enter the Web server through browser, web client. And control 4 Channel Relay module with simple click.
