Use Ethernet Shield to send data from Arduino Uno

Projects Networking, Protocols, and Devices

This is a general question. I am new to Arduino but have successfully generated some useful sketches. One involves using an Uno at a remote location to turn a device on and off. The sketch is basically a thermostatically controlled heater. I have searched around the Arduino site but found only one tutorial related to this topic. I read the tutorial about sending analog pin data from the Ethernet shield to a web browser on a computer. Can data from inside the application running on the Arduino board be taken in by the Ethernet shield and then be made available remotely to a browser on my computer connected to my LAN over CAT5 cable? The data I am interested in is the temperature output of a temp sensor (currently Adafruit) connected to the Arduino, a mapped output value derived from a potentiometer connected to Arduino board A0 representing the thermostat set point temperature, a single-bit indication of whether the heating device being turned on and off by the Arduino board pin 7 is in an on state or an off state, and elapsed day, hour, minute time data in the Arduino representing how long the heater has been in a current on state.

I hope that I am not sounding too ignorant here.

Thanks,
Ken

We all learn. With only one post, you can expect to do a lot more of it.

Check the examples in the Ethernet section of the IDE. There are a couple of webservers.

If you don't want to deal with webservers and webclients, take a look at RS485 : https://create.arduino.cc/projecthub/maurizfa-13216008-arthur-jogy-13216037-agha-maretha-13216095/modbus-rs-485-using-arduino-c055b5
