![]() I explained last time that if the light sensor is put in a dark space, its resistance goes up, and if it’s put in a bright place, the resistance goes down. What Can We Do When a Light Sensor Is Hooked up to a Network? This will allow us to connect a LAN cable, and enable networking on the Arduino. Last time, we displayed the brightness data from the light sensor using analog input on the Arduino. Now, we know how to process both input and output with the Arduino! Today, I’d like to take it a step further and connect the Arduino to a network. By enabling network capabilities on the Arduino, the project possibilities open up. Despite its small size, it can become a web server! This time, I’d like to make a program that turns the Arduino into a web server using a module called the Ethernet shield.
