ok so here are some images. its powered with adapter 9v and stabilized with stabilizator. in cover of rs232 is max232 and some resistros and caps, its working because i can upload sketches with it. there are some extra wires that are not connected

yes.

thanks guys for fast replies. i realized that my microcontroller is still working  smiley-lol.  i think that problem is in arduino because i dont have one. i'm using atmega328 that's already bootloaded http://www.rlx.sk/product.php?id_product=556.im using ic max232 and serial port for communication.BTW im sure that i selected the right target microcontroler because both of them are atmega328.

i tried everything with multimeter connected to leg of microcontroller and it was fine. this is error i get while uploadnig
avrdude: stk500_paged_write(): (a) protocol error, expect=0x14, resp=0x64
avrdude: stk500_cmd(): programmer is out of sync

I tried to use arduino as isp. i connected everything correctly and upload the sketch. i pressed the burn burnloader button. after 30 seconds i get error and my microcontroller break. now it's not working. i tried it again and i break another microcontroller.can anybody help me? did it happend to you? BTW while burning led   was blinking very fast with low light.

thanks guys,
i want to burn the bootloader with arduino as isp but how to connect it to ATmega1280?

Hey guys,
Im not sure abouth one thing. Arduino uno need atmega328 with bootloader. It won't work with normal atmega328. Does ATmega1280 has any bootloader or i can use every ATmega1280. I'm telling because i was thinking about build my own arduino mega smiley
Thanks.

Hi guys,
I have litlle problem with l293dne.i was making this: http://letsmakerobots.com/node/2074
but it didnt work. i realized when i get 5v to input(pin 2 on l293dne) it does nothing however when it get ground to input it works.did it happen to you? can i fix it?
