The Arduino is open source for both software AND hardware.
There are many alternative hardware versions out in the wild, so one is almost
certain to fit your needs. Definitely not one size fits all.[ Reply to This | Parent | # ]

I thought you might be interested in the new attachment I have
ordered.
The Gertboard is an add-on GPIO expansion board for the
Raspberry Pi computer. It comes with a
large variety of components, including
buttons, LEDs, A/D and D/A converters, a motor controller,
and an Atmel AVR
microcontroller. There is a suite of test/example programs for the
Gertboard,
Thus, in order
to use your Gertboard with
the Arduino IDE, you need to know how the Arduino pin number relates
to the
labels on your Gertboard. The table below shows this
correspondence.
Thus, you can program the Raspberry Pi in Python
to use the General Purpose Input Output pins with the interface circuits,
buttons and LEDs on the Gertboard, Also, you can run the Arduino IDE on the
Raspberry Pi and use the I2C pin on the GPIO to program the Arduino processor on
the Gertboard and use the same features.
I could be gone for some
time.

| I have recently repaired my HTC Legend phone, and was thinking about rooting it
the other day. Not actually done it yet, just looking at the preliminariess, but
it turns out that HTC, in their developers web site, have all the tools for
unlocking the bootloader. What is more, the kernel source is not only there (as
required by GPL) but very easy to find. Coupled with the announcement from
Googorola (or is it Motogoogle?), it seems that some very mainstream
manufacturers are very much on side, as regards the freedom to modify the
functionality of their products. Oh, and I will shortly be doing some serious
work on an Arduino, but have not yet obtained a Raspberry Pi (too busy), unlike
some of my work colleagues. Apart from Apple, the Vile Monopoly and a few
others, the world has moved on from the walled garden. Those who do not will be
left behind. [ Reply to This | Parent | # ]

Well, when I was a kid I could program Megatek and DEC GT-40 graphics hardware
down at the "bare metal". While some Systems On Chip (SoCs) are
mostly open, graphics processors (GPUs) are still locked up and inaccessible
except through opaque binary drivers.
Another major walled garden is Field-Programmable Gate Array (FPGA) bit streams,
so you can only use the vendor's software to program and re-program the FPGAs.
IMO this has prevented 30 years of creative independent work from happening with
FPGAs. IMO FPGAs could have become the primary supercomputing engines if they
hadn't been locked down.
