INTRODUCTION 

In this tutorial, we will use the MDuino21+ PLC to create a Simple Web Server. Using the Ethernet library, we will be able to answer a HTTP request with the Ethernet shield. After opening a browser and navigating to your Arduino based PLC with Ethernet’s IP address, your Arduino will respond with just enough HTML for a browser to display the input values from all six analog pins.
