Can you define "does not work"?

Does it do anything? What do you expect it to do? What does it actually do?

I see a whole lot of text in RAM that should be in flash.

3

it supposed to act as a server to controll the led and servo

i have the code for ethernet thats works but i tried to convert it to wifi this is the ethernet code

Delta_G:
Does it do anything? What do you expect it to do? What does it actually do?

merkzilla:
it supposed to act as a server to controll the led and servo

I guess 1 out of 3 ain't bad.

6

well if you put the ip address in the browser a webpage to control the led and servo is supposed to appear.... al though this code for the wifi shield uploads with no errors it simply does nothing even in serial monitor

7

Which Arduino are you running that code on? How much available memory do you have?

http://playground.arduino.cc/Code/AvailableMemory

Why are you not using the F() macro?
client.println(F("HTTP/1.1 200 OK")); //send new page

Why are you NOT printing anything to the serial port in setup()? Why are you NOT printing what you get from the client?

8

i suppose idk...? im a noobie i dont understand but the original code didnt have this as well

9

i suppose idk...?

You suppose that you don't know which Arduino you have? That'll be a problem.

10

oh no i have the arduino uno sorry i was saying im not sure about the rest lol

11

Did you read the link about available memory? Did you test how much you have?

Did you take the hint about using the F() macro? Did that change the amount of available memory? (Of course it did, or would have).

Was that enough?

12

i tried using the f macro that i beleave was correct example.

.....client.println(F("HTTP/1.1 200 OK"));....

but it said something about F not being declaired or something.....
this is the most working code i have so far.......

and i says im using 92% of th ememory
Global variables use 1,885 bytes (92%) of dynamic memory, leaving 163 bytes for local variables. Maximum is 2,048 bytes.

14

leaving 163 bytes for local variables.

That's nowhere near enough.

but it said something about F not being declaired or something.....

I'm 100% certain that the compiler stated EXACTLY what was wrong, and the line on which the problem occurred.
