Hong Kong. Ethernet Shield allows an Arduino to to connect to the internet and to read and write a microSD card. This shield use Wiznet W ethernet chip. This shield is also has a microSD card socket to interfacing with a microSD card. To make a program using this shield is very easy, because there is a library from Arduino both for Ethernet and SD card. The Arduino server will wait for the connection from cilent. The client will send commands to the Arduino via port 23 of TCP port numbers.

After that, we must make server object and string variable called commandStr for storing command from client. If there is a character sent back read it and send it to the serial port. Ignore anything else that the server might be sending. You need to read the data in a while loop, looking at both client.

You need to store the data in an array of characters, or preferably not a String. Start by dumping the code you have in loop. All of it. Concentrate on getting something to display before you worry about how to display it. Move the code to make the request into loop. Use a boolean flag to send the request only once. Then use a while loop, checking both client. Good advice, thanks. I did as you suggested, and went back a few steps. This amended code works to display the characters from the web server on the Serial Monitor.

Can you point me in the right direction on how to do this? My initial thought would be to put this. On each pass through loop , you read at most one character. Move one step at a time. Now, to collect the data in an array, you need to define an array and an index into that array where in the array to put the character.

As it is right now, the Arduino stops doing anything but that infinite loop when the server closes the connection. Many thanks PaulS for your help.
