Why the Arduino Won and Why It's Here To Stay 224

    There was a time when it was difficult and expensive to develop embedded applications. Then MicroChip came out with the PIC. The tools were free. There was lots of helpful documentation. You could build a PIC programmer out of junk box parts.

    If you were a small developer, you wouldn't bother with a company like Philips (and the others) whose tools were expensive and whose documentation was Byzantine.

    Arduino is one step better. It was designed to be used by artists. There are tutorials for everything. It is SO easy to use.

    Of course, Arduino isn't a chip, it's a little board. The chip is Atmel's AVR. I don't know what Atmel did to deserve their good luck. I'm guessing that the hard work of the Arduino folks has really increased Atmel's market share.

    The lesson here is that it isn't the goodness of the chip. (The early PICs were really unfriendly to C compilers.) You can have the best chip in the world but nobody will use it if they aren't properly supported.

      Using a Dallas Smartsocket JEDIC socket with a 6564 SRAM chip made a great development environment.

The ARMmite Pro is a great little board to play with, ARM 7 running at 60mhz, can be programmed using Basic or C, and (apparently) pin compatible with Arduino, all for $30.

    • To be honest, I think you're giving Arduino a little less credit than it deserves. It's not just popular just because it uses the ATmega. It's popular because it greatly simplifies the whole process from start to end. If you're concerned with bloat in the various libraries, then why don't you fix them? They're not binary blobs.

      Really, any dev kit from any half-way decent company will be just as painless to jump into. The difference is that the Arduino is so much cheaper than professional dev kits. While EEs who like to tinker in their spare time (like me) might not mind shelling out $250 for a versatile kit, novices (or people who don't need the extra muscle) are understandably put off.

      The Arduino fills that niche, and is much nicer to work with than the old basic stamps I had to put up with in college.

    Most of my coworkers are old-school embedded programmers. Many of my friends are Arduino-enthusiasts. The Arduino has a vastly easier learning curve: you plug it in, open a window, and hit 'download' and your code is on the machine and running. People who are used to embedded programming are fine with setting up a development environment with libraries, handling source files, telling the IDE what programmer hardware is being used, what target hardware is begin used, what oscillator frequency and which fuses to set, but that's simply overwhelming to someone who just wants to turn relays on and off to power an art project.

    And once a lot of people were using it, they all started releasing their code. Sure there are other great code repositories, PIClist, AVRfreaks, but many of the people there are pretty DIY so they'll exchange snippets of code that they build into something finished. Arduino code is often complete: download this program to do this entire process. That mindset has attracted lots of people, who have contributed even more code, so it benefits from a networking effect, so now anyone who is releasing anything for the electronics experimenter market has to provide an Arduino sketch that handles the hardware being offered -- and that drives it even further.

    There are cheaper platforms, there are faster ones, there are ones with much better hardware (and some that are all three, the MSP430 being a likely example) but nothing that combines the simplicity and codebase of the Arduino.

    (a listing can be found at [] )

    I have tried to use Arduino boards in the past, and while they're really cool for hobbyist stuff, they are very hard to integrate into battery-operated things:

    1. The operating voltage is 5V (some may be 3.3V, I forget) and draw a lot of current. Batteries that supply this kind of voltage are HUGE. It would be really nice if they had a design that was optimized for low voltages and low currents, like for mobile sensing, so that I could use coin cells.

    2. The devices are really memory-limited. The Uno, which is probably the most popular, has something like 2kB of ram. I used the board to interface with some sensors for tracking a flight trajectory on-board, and I could only record a few seconds of data before running out of room. Wireless transmission wasn't really an option because of power (= more batteries) limitations.

    3. Connecting to USB resets the board, wiping the memory, unless you cut a trace on the board. This is supposed to help facilitate loading new programs, but becomes an annoyance if you wanted to use it to transfer sensor data stored on-board to a computer. When you cut the trace to disable the autoreset, it becomes difficult to time the reset button manually so that your program uploads.

    Overall, as an EE, I was very impressed at how easy it was to use, but I think the issues I mentioned warrant some fixing if Arduino is going to be used for things like sensing.

    Arduino is basically a platform for home users. Just like BASIC was in the 80s. That doesn't mean that it's bad, or to dismiss it, just that it needs to be placed in context. While the Arduino family have no doubt sold many, many units what does that actually mean to Atmel? In terms of the MILLIONS of devices they sell every month, the number bought by amateurs is a drop in the pot.

    Same goes for Microchip and the PIC family (processors, not development boards). I would expect they are quite happy to cede a few 100k's of chips over the past few years, given that their main business line is everything that has an embedded processor.

Even I got a EE as part of my double CS/EE major 15 years ago, I haven't really done any electronic after college. Arduino provides a quick way to get started. Out of box with easy to use IDE, I can make stuffs entertaining my kid and myself in no time.

    The experience getting into Arduino reminds me a lot of the beginning days of Linux. There are more mature commercial options out there (e.g. Solaris, IRIX, even HP/UX) and other competing open source like Net/FreeBSD. Even GNU/Hurd was making progress. But one thing Linux got was a friendly community of beginners. Going through the Arduino forum gave me the same feeling of going through Linux forum back in 95: a lot of excitement about this and willingness to help each other and share. That's defintiely one thing other communities lack. One gets "did you real the source?" reply posting anything to a BSD group.

    That's almost parallel to where Arduino is today. There are no lack of better or cheaper alternative but most of them are either established embedded communities or serious lack of documentations. Not friendly at all for the beginners. Arduino gives the beginners a friendly place to get started.

    And Arduino goes behind just a AVR based board. It's really a ecosystem with standardized IDE and peripherals. Most people's first critics of Arduino, especially those already in the hardware hacking, is the use of AVR and often cite 8bits and the shortage of AVR last years as problem with Arduino. However, I don't really see that as a short coming of Arduino. I just got a Leaflab's Maple which is a ARM based board with Arduino compatible pin layout and IDE. Getting my projects over to Maple from Arduino is smooth. I don't see Maple as a competitor to Arduino but a member of Arduino family.

    The article is right on. There will be a lot of competitors now Arduino is on the spotlight but most of them will fail because they don't get the point of Arduino. It's not about raw CPU power or fine point of the system components, it's about community. And ones don't win the hearts of the community by belittle the community's core.

Recent investments will yield a slight profit.
