I am new to arduino, I need answers on simple matters....

  • Is there a problem if I remove atmega328 then put it back correctly and it does not work?

-how to reset the duemilanove?


I've removed the chip then replaced it, and it still worked. I don't know what your problem is.

Pressing the reset button?

... then put it back correctly...

Sure? Are you sure, you 've not bent a pin under the circuit while putting it back? Or stressed the board if not on a flat surface when you put the circuit back?

Remove it again and inspect the pins to make sure none bent inwards. Also be sure it is inserted with pin 1 of the chip matching pin 1 of the socket.
