Hello,
I just bought my first arduino - arduino mega 2560. how can I use this with the ethernet shield to communicate data from 7 sensors connected to the arduino mega to a remote server?
your response is highly appreciated.
You make a TCP/IP connection to the remote server and send it the stream of bytes it requires. Are you going to write the remote server code or is it an existing server for which you have the protocol specification?
Start by displaying the sensors to the Serial port, so you can see them in the serial monitor.
When it is hard to upload them to the remoter server, you could try ThingSpeak.com first. You get nice graphs of your 7 sensors.
