When I got my first Arduino the first thing I thought was “Wow! I’d love to be able to control this thing from a web page!”, but of our course I didn’t have an Ethernet shield. So recently I decided to grab a shield from Amazon and see what I could do. First things first I needed to create a simple sketch to draw a web page and accept input. So in this tutorial that’s exactly what we will cover!
HOW TO CONTROL AN ARDUINO FROM A WEB PAGE
In this project tutorial we’re going to setup an Arduino with an Ethernet shield that will allow us to control a blue LED from a web browser (of course you can use another color if you desire!).
The first thing you need to do, before we even think about controlling an Arduino from a web page is to connect the Ethernet shield to the Arduino. It simple aligns with the pins and presses down. Don’t press it down too far however, or the bottom of the Ethernet shield may make contact with the top of the USB port. This could cause your shield to short out. The shield used in this project is the Wiznet W5100 variant made by Sunfounder (a clone of the official Arduino W5100).
