Reusing Board

Do I have to buy an Arduino Duemilanove for every project I make? Or is it possible to program the microcontroller and only put that in the project, then buy another microcontroller to use with the Duemilanove for any other project I have?

You posted this question already the other day....

You can buy chips preprogrammed with the bootloader. You jsut need a few parts to make a standalone setup: Please have a look on the palyground article:

Thanks for the help :)

If you download the schematics from this project:- http://www.thebox.myzen.co.uk/Hardware/Pendulum.html There are versions that use a ready built arduino and a make your own using bits. You can study them to see what you need in your applications.
