You buy a new board from a supplier that supports the Arduino that hosts the site. (there's been a split, official boards maker partner broke with, does not support the software side of the company.You buy some blank 328P-PU chips if you're going to 'eat' chips and bootload them.http://www.gammon.com.au/breadboardEverything you need, step by step, multiple ways like 3.3V 8MHz no crystal operation.. At 3.3V you can interface directly to 3.3V devices, a 5V board needs voltage leveling.The Mighty 1284P is also given treatment. Want an AVR with 16K RAM? I get them down around $7 each plus shipping. It's pretty loaded for not having to deal with SMT.
