Alright gentlemen, here's the story.

In 2009, I was doing a science fair project on hacking a Roomba. I bought 3 Arduinos: 2 Duemilanoves and a Diecimila. I was 11 at the time, and obviously shorted something out because the three Arduinos and the Roomba are all dead. Now, the Arduinos power up and all, but I can't program them. I think that I shorted the power or something and the FTDI chips got fried.

I just bought an Uno R3 from Sparkfun and another one from Radioshack because I'm impatient and didn't want to wait for the Postal Service to deliver my package. The Loop-Back tests failed on each old Arduino. I'm considering replacing the FTDI chips but I've never SMD soldered or hot air reworked before. Does anyone think I can use them for projects but program the ATmega168 chips on the Unos?

Thanks, Alex


You can remove a couple of Resistors and isolate the ATmega from the the FTDI chip, reuse the board that way.

Dees anyone think I can use them for projects but program the ATmega168 chips on the Unos?

You can program the 168 in the Uno board just fine.  You might need to use the "Duemilanove w/ 168" option from the board menu.

The board menu is misleading.  It is really "which boot loader do you have."
