While working on an Arduino-start-here tutorial, I am trying to find the most "fail proof" way to hook up an Arduino.
Now, if I could decide what OS and connection everyone had, it would be easy as this:
* Install Ubuntu 10.10 OS on your PC
* Install The Arduino IDE (and write your program)
* Insert an USB-FTDI cable from conputer to Arduino board
* Select the serial port
- And done, you can now press the "upload"-icon, your program will compile and upload.
The above is so far the easiest I have found.
