just bought an Arduino Duemilanove ATmega 328

i get this error when i try to upload the program blink

avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

Hey, welcome to Arduino!:smiley:

Sounds like you've got the wrong board selected, take a look under Tools, and scroll down to Boards. Then from there, select Duemilanove 328. Also, make sure you've got the right COM port selected! (always 2nd one in the list for me)

Best of luck:D

i selected the right board and theres only COM1 available
i guess ill try it on my school computer tommorow then :-/
thanks for the welcome

The Arduino board first has to be plugged into the PC's USB port. The PC will then reconize the connection and 'create' a new comm port number, which is the one you need to select. If the PC doesn't reconize the connection when plugged in then there is something wrong with the USB driver installation.

Lefty

im so happy!!
after about 2 hrs playing around with this thing
i ran the MS-DOS batch file and when Arduino came up i checked under the serial port and it came up with a COM3 now its working ;D
ive never been so excited about a 1 sec blinking led before ;D

ive never been so excited about a 1 sec blinking led before

But you will be again, the most complex circuits and wiring can be shown to be working with a blinking LED.

That is when you know it is all working, it's all down hill after that. This even applies to most professional engines I know. :wink:
