Description
Arduino Uno - R3Arduino is an open source physical computing platform based on a simple i o board and a development environment that implements the Processing Wiring language. Arduino can be used to develop stand alone interactive objects or can be connected to software on your computer (e. g. Flash, Processing, MaxMSP).

Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).
This is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations).
This allows for faster transfer rates, no drivers needed for Linux or Mac (inf file for Windows is needed), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc.
Note: The Arduino Uno R3 requires the Arduino 1.0 drivers folder in order to install properly on some computers. We have tested and confirmed that the R3 can be programmed in older versions of the IDE. However, the first time using the R3 on a new computer, you will need to have Arduino 1.0 installed on that machine. If you are interested in reading more about the changes to the IDE, check out the official Arduino 1.0 Release notes.

Love these bowls
Size: 12 Ounce, 150 Pack, Color: White
Love love love these bowl. They are so sturdy and amount for price is perfect. I use these at parties where I am serving chili and soup and they hold up great. Absolutely love these bowls and I don't feel bad when the party is over and they're all in the trash.

Good, but not long lasting.
Size: 32 Ounce, 50-Pack, Color: White
These are good bowls, nicely-sized for salads & bulkier meals. That last reasonably well for soups and other liquid-based meals, but I would not push it too far. I would not use them for something liquid that might sit for very long, such as something intendeo to be eaten while conversing.

Great salad bowls as well as cereal bowls.
Size: 16 Ounce, 125-Pack, Color: White
Nice bowls. They hold a bowl of cereal very well. I like how biodegradable they are makes me feel less guilty of using paper.
