Arduino web server showing DHT11 data

In this example we will use a DHT11 sensor and display the humidity and temperature on a web page. You can use any temperature sensor but the DHT11 is fairly low cost and there are libraries written for it, it comes in modules and even if…

Arduino ethernet shield read switch example

In the previous examples using the Ethernet Shield for the Arduino we controlled an led and an rgb led using pins as outputs but you can also easily monitor the state of an input, in this case we will use a switch Basically it will be a web…

Control an LED from a Web browser with an Arduino

A simple way of adding network access to your Arduino Uno and Mega is the Ethernet Shield, there are a few clones out there but they all generally work the same way. The Arduino Ethernet Shield allows an Arduino board to connect to the…
