Arduino Duemilanove!

I just got a brand-spankin’ new Arduino Duemilanove from
Adafruit Industries and I just had to share the excitement. I downloaded their IDE and installed a simple program that pulse width modulates pin 9 making the LED fade in and out. The board can be powered either from the usb, the power jack or an external battery, which the board automatically selects depending on which one’s plugged in. I’m quite a fan of just having to plug in one cable, that being the usb, for power and data transfer. Thanks to their from-the-factory installed bootloader, uploading new code is a piece of cake. It takes care of copying code directly into flash and executing it when the device fires up. Simplicity is beautiful isn’t it? Here are some specs taken from the arduino.cc site:
