Please supply ALL the information required to answer your query. Think that you are asking someone who does not know what you have built and describe everything you can.

Or you could use an older version!!!!

You need to buy a programmer - you can get them from eBay starting for $3

OR you have  a faulty Eleven or faulty USB cable, what do Freetronics say when you emailed them about the fault with your new arduino?

Please define 'didn't work' - This tells us nothing of any use - have you connected all the wires up correctly? Are you powering the module from the arduino? how did you connect it to get 'works perfectly without arduino(connected directly to PC)' - do you get ANY output on your Serial Monitor? If you do, what do you get.
36  Using Arduino / Networking, Protocols, and Devices / WIFI shield drops connection - a solution here. on: July 11, 2014, 03:42:59 am
Hi all,
           While designing a remote WiFi connected logger for a client, I had issues when the unit was installed on his WiFi network, the connection would reset for no reason (it was a BT business hub, so no surprises then). After a look around the forum, the web site and google, there was no solution that I could find. So I came up with this little piece of code :

Code:
void isWiFiConnected()
{
  IPAddress ip = WiFi.localIP();
  if (ip[0] == 0)
{
 Serial.println("ERROR!!!!!");
 status = WiFi.begin(ssid, pass);
    // wait 10 seconds for connection:
    delay(10000);
}
}


I call this in my main loop - instead of dropping the connection and being unavailable until the unit is reset, it now reconnects if the IP Address starts with a 0 - e.g. 0.0.0.0

you don't - you make it.

You will probably get a better response of you post in a labview forum!

I've used the cheap digital cameras from ebay, and rigged the shutter release with relays for some, and transistors for others.

or press and hold reset until the sketch size shows and release the reset button.

you do not use a programmer when using the ftdi - burn the bootloader with your usbasp, then unplug it and connect your ftdi. all you have to do is click upload (or the tick) with any example (blink is a good choice).
43  Using Arduino / Project Guidance / Re: AREF pin setup on: July 07, 2014, 01:50:33 pm
Yip, thats fine - as long as it's not over +0.5V higher.

Wow - just typed some stuff into google with the word keyboard and arduino, and it gave me lots of links . . Maybe someone broke your google?

Please give a link to the board you purchased - there are a lot of Chinese 'clones' that do not use the ftdi chip.
