The whole Arduino thing sort of puzzles me. I guess this is a case of the right product in the right place at the right time, because the idea of "a PCB with a microcontroller on it" is not new. Nicely provisioned full took chains are not new. Stacking connectors to add functionality isn't new.<div>
<br></div><div>I'm also confused by why programs are called "sketches" and daughter-boards are called "shields". And while I think it's a Good Thing, you'd think that C would NOT be a natural language for getting people interested (I would have sooner suspected BASIC or even Forth).</div>
<div><br></div><div>At least it's enabling people who wouldn't otherwise get involved with a microcontroller to do something interesting with them. Even if blinking a LED is what they considering exciting.</div><div>

The Arduino is a serial bootloader enabled AVR (ATmega8/168 family)<br>
microcontroller board. The high points:<br>
<br>
- lots of microcontroller stuff is all wrapped up, so you can program<br>
in pretty high level C on a microcontroller. it's designed for<br>
non-technical types (e.g. artists), but this lazy technical type<br>
appreciates the wrapper. (:<br>
<br>
- serial bootloader and built-in USB/RS232 hardware, so no external<br>
programmer required<br>
<br>
- IDE is free and cross platform (linux, os x, windoze)<br>
<br>
- if you get tired of the Arduino wrapper, peel it back and use the<br>
avr-gcc toolchain, still free<br>
<br>
- several variants and peripherals. Plug-in daughterboards are called<br>
shields and can be stackable. varieties include protoboard, motor<br>
controller, ethernet, etc.<br>
<br>
<br>
I've used the base system to build several balloon experiments, and<br>
have flown the software running on custom hardware several times. I'm<br>
currently designing a couple of shields to use actual arduino CPU<br>
boards (instead of custom PCBs) to make a modular hardware library for<br>
putting together balloon experiments.<br>
