Introduction

The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter.

"Uno" means one in Italian and is named to mark the upcoming release of Arduino 1.0. The Uno and version 1.0 will be the reference versions of Arduino, moving forward. The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform.

I have played with arduino in university. Not uno, but mega. It has more pins, but bugeer too. By the way I like arduino software. It isn't hard to program. You just need some C programming knolage. By the way I'm using it on mobile robots moustly. Students an some teachers are making 3 diferent mobile robots. Trying to get price in "Robot intelect 2012"

I think most of us already have an Uno, or other types of Arduino's. For me I would rather someone that is new - or doesn't yet have an Arduino for one reason or another, gets a chance to get one. This way I don't have one sitting collecting dust

Hello - sorry for the inconvenience and thank you for the feedback. There is an issue with the display of the applicant list for RoadTests, but applications have been saved ok in our database. I will update with further progress in resolving this issue.

Thank You,
Drew

I enrolled earlier this afternoon. When i log in again (now, maybe an hour or 2 after I enrolled), I only see myself as someone who enrolled.

I am amazed too at the fact that no one else has enrolled for the road test. Surprising!

I think many people have already enrolled (including myself), but there must be a bug in the website.
