I have a problem with my arduino board. have just started in schoole again after the summer, and before the summer my arduino did work. Then suddenly after the summer it didn't work. Just before the summer i copied the 0007 version from my computer to another computer, can this have made the problem?
I tryed to download the 0009 version but it sead that there was a problem in the zip komprimated foilder.
Well this is not all. Then I reformated my computer and i still can't download the 0009 version because it still tells me that there is a problem in the zip komprimated folder. then i have tried to download the 0008 version. This one i can download, but i can't get it to work with the board. When i try to upload it seas that i sould reset the board... and ofcaouse i am resetting the board when i am uploading.
i can't say anything about your downloading or zip-file issues (it worked for me though, on windows and mac with 0009).
regarding your problems uploading in 0008... did you select the right serial port in the software menu? (>tools>serial port)
when you reset the board you have a few seconds to upload the program. if you're computer is too slow, it might be missing that timeslot. try resetting the board shortly after you click "upload program" in the arduino IDE.
another thing to check would be if your bootloader is working: connect a led to pin 13 and ground. if you power the board (or reset) it should blink three times. if it does not, your board might be not ok.
if you have access to another computer, try it there. disconnect anything but the usb and led on pin 13 until you find out whats wrong.
