Not in the order which he has it. And it depends on the
alternate English meaning of "came" to translate the same in Latin. I
*don't* know Latin (except enough to recognize the warping of the
traditional saying). :-)

My arduino came from Radio Shack's close out. I started with Blink, got
a GRBL driver shield from China and found GRBL and EFL software to stream
g-code to the arduino uno.
Just now it's sending 3D g-code from a huge down loaded file to test
the setup. This is way outside anything I know about.
There are some better looking free programs out there but so far the
Engineering For Less free program seems to work OK. I don't have to write arduino code with the EFL CNC software. It comes up on google.
No CNC machine yet, just 3 steppers and a 12 volt power supply twirling little paper tags. Great fun!

I dunno, I use Arduino 1.6.0 (not the latest) on Windows 7 & 8.1, with notepad++ as the editor, and it just seems to work. Have not yet tried under linux, but I may be moving in that direction soon.
I'm not wild about having files stored all over the place - why are libraries being stored in my Documents directory? But I just plug it in and it goes.
For some other products, I just use the gcc tools directly, but for quick & dirty, and to avoid having to write device drivers from scratch, Arduino does save a bunch of time.
Actually, the Beagle Bone is a better deal. You get a full Linux system,
with all the networking features available. It also has 2 200 MHz 32-bit
microcontrollers that have about a dozen pins brought out for each, and
shared memory to the Arm CPU. These are great for bit-banging odd
protocols, generating step pulses or some other thing that isn't directly
supported by on-chip peripherals.
I updated a laser photoplotter I built about 16 years ago, using a DMA card
on the ISA bus, on a Windows 95 computer. Not only could the
microcontroller emulate the DMA card, but it could also unpack run-length
encoded data in real time. File sizes of 1000x1000 DPI raster images get
big, so compessing them is really nice.
I've used various versions of the Beagles for network appliance devices
before, and they are great. You can use Glade to develop the user
For mine, I bought some terminal boards that plug in the Arduino from Jameco
Electronics. Also I bought a board with a LCD display and some buttons from
Hobbypartz.com. Other boards have more capability in pure processing power,
but the basic Arduino's work with 5V logic and have the chip in a socket, if
you burn it up you can replace for ~$5 with the bootloader in place. The
Arduino works with their langauge but you can also us "C" language, so get
the documentation for GNU C for more capabilities.
I wrote a program that uses timers modeled after Allen Bradley PLC timers.
I also have BeagleBone Black and Raspberry PI, they have processing power
and lots of memory but I don't feel like I control all the code like I do in
an Arduino. Also I can't replace the processor as easily if I make a
mistake in the wiring.
