Hello,i wan to ask something...i wan to supply >5V voltage for my Arduino duemilanove Atmage328,but i mistake to put wrong pin to the 5V Connector Pin,now my arduino cannot function at all...
Now,My question is isit arduino broad spoil or IC Atmega328 spoil???

thankz u...

I think you have fried the ATMega 328 and the ATmega 8U2 (they work on 2-5V), and maybe all those LEDs on that board. I think you should get a new one.

I think the Atmega328 will be burnt if the voltage you applied is more than 6V, or even 5.5V. You can try changing the Atmega328 first, but you will need to burn the bootloader first. To check whether the USB chip is working or not, just simply plug in to USB board without additional power supply. Computer should detect a new COM port. If it does not, your USB chip should be gone too, sorry!

Now i make the experiment see my board spoil or IC spoil,then i take my friend Arduino duemilanove IC Atmage328,to plug in my board also is Arduino duemilanove.when uploading,everything will be fine,can function as before...

Then i think is IC spoil,after that i order the IC-ATMEGA-328 from cytron.
when i get it,i plug in to my board...it cannot upload,when uploading,it will show "Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions".
then i take this new IC Atmage328 to plug in to my friend board,same problem...show this word also.

what is the problem about this??? isit have other type of IC Atmega328???

thanks a lot.

Does that Atmega328A you bought from Cytron contains the Arduino Bootloader? The Arduino requires that the chip must have that small program inside for programming purposes.

I don't think the Atmel chip from Cytron contain the bootloader code. We need to program the boot code by our own.

Nope! The chip you've bought from cytron does not have a bootloader. You need avr programmers to bootload it. You should buy those with bootloaders.

Why don ask Cytron to sell those chip with arduino bootloader?

ya,why cytron don't have sell the chip with bootloader???then how can i find this small program of AVR???

You may need to copy the bootloader to the chip by yourself. There is an AVR programmer sold in Cytron.
