How to Simulate a Web Browser with an Arduino

Are you interested in controlling your Arduino from a web page? With the help of an Ethernet shield and some simple coding, you can create a web-based interface to control your projects. In this tutorial, we will show you how to simulate a web browser with an Arduino and use it to control a blue LED.

Hardware Requirements

To follow along with this tutorial, you will need the following components:

* An Arduino board

* A Wiznet W5100 variant Ethernet shield (such as the one made by Sunfounder)

* A blue LED

* A 10K ohm resistor

Wiring Diagram

The wiring diagram for this project is simple. Connect the positive leg of the blue LED to pin 2 on your Arduino board, and the negative leg to a 10K ohm resistor. Then, attach the other end of the resistor to ground.

Software Requirements

To create a web-based interface to control your Arduino, you will need to write some code. The following code should be uploaded to your Arduino board:

```

// The Geek Pub - Controlling an Arduino Pin from a WebPage

int blueLED = 2;

String control;

void setup() {

pinMode(blueLED, OUTPUT);

}

void loop() {

if (control == 'on') {

digitalWrite(blueLED, HIGH);

} else if (control == 'off') {

digitalWrite(blueLED, LOW);

}

```

This code uses the W5100 Ethernet shield to create a web page that allows you to control the blue LED. The `control` variable is used to capture the URI query string data from the web page.

How to Use the Web Interface

To use the web interface, simply connect your Arduino board to your PC via USB and open a web browser. Navigate to the IP address of your Arduino board (in this case, 192.168.1.212) and you should see a simple web page with two buttons: 'on' and 'off'. Clicking on one of these buttons will control the blue LED accordingly.

With this tutorial, you have learned how to simulate a web browser with an Arduino and use it to control a blue LED. This is just the beginning - you can use this technology to create all sorts of interesting projects that interact with the internet. With some creativity and experimentation, the possibilities are endless!
