You'd have to set your router setting to get the arduino that static ip. You'd need the  arduino's MAC address.

Isn't the  your router's dhcp an issue? I'd give the arduino server a static ip.

yup, worry about RAM.
using the correct datatype helps like don't use INT or LONG if you know the number is not more than 10.

where is this other place? work? school?
password change?
5  Using Arduino / Programming Questions / Re: Time to record 1 analog datastream using I2C and SD card logger? on: April 21, 2014, 07:34:50 pm
That seems like it's too fast for the sd card. It takes time to open and write to file.

Maybe save the data to an array and then save it to the sd card but I don't think the arduino has enough memory to save thousands of records.
6  Using Arduino / Programming Questions / Re: Convert String (5-byte HEX) received via Serial to uint64 for nRF24L01+ address? on: April 17, 2014, 09:05:41 am
I think there's a c ++ function you can use

Strtoll

7  Using Arduino / Programming Questions / Re: Webcam on: April 16, 2014, 11:40:05 am
What you probably want to do is use the ardunio to control servos that controls the position of webcam and your vehicle.

You probably want something like this.

The video streaming is handled by another component. Not sure what. It looks like some portable wifi component.

If you want remote control like from thousands of miles away, you probably will need a server.
8  Using Arduino / Programming Questions / Re: arduino UNO and Arduino mega differences in program on: April 15, 2014, 06:20:20 pm
different boards call for different pins.
9  Using Arduino / Programming Questions / Re: Library error: 'Some thing' was not declared in this scope drive me Nuts on: April 14, 2014, 03:54:23 pm
Are you saying that I can't use serialEvent1(), serialEvent2() and serialEvent3() in a library in the same way that I use it in a sketch?

What he's saying is you better stick

 Uart_WIFI:: in front of

serialEvent1() in the function definition.

You might need to include <arduino.h> in your source file since you're using arduino's serial events.
10  Using Arduino / Programming Questions / Re: Help with modulo. 25%10 always rounds off to 6. on: April 13, 2014, 07:23:43 am
You're dealing with decimals not int. try float .
11  Using Arduino / Programming Questions / Re: How to return the class an object belongs to? on: April 12, 2014, 08:32:30 pm

Oh, good to know!
12  Using Arduino / Programming Questions / Re: Parsing large strings on: April 10, 2014, 10:27:49 am
you have a sd card component on the shield. Why not use that to store the html?

RTC is the easiest way to go.
15  Using Arduino / Programming Questions / Re: basic c question on: April 08, 2014, 12:45:53 pm
yup,
you have to use strcmp correctly

this site is the place to be where you have to code C.
