Beginners Adruino ACTUAL COSTS

Hi,

I had a few questions concerning Adruino and I did not know where else to post them. I hope this is the right part of the forum.

I was reading an article, a lot of which was pretty obvious to me. This is the article >> http://www.extremetech.com/computing/148482-the-true-cost-of-a-raspberry-pi-is-more-than-you-think . I am a student and I am going to be studying compute science and I was interested in getting started with Adruino as well, mainly Adruino and Technic robotics. I am also interested in a lot of the Android ad Adruino hacks I have seen on the web.

I have little to no knowledge of the above and I am an absolute beginner, hence this post. However, I waned to get started and I did not know where to being, since I have very little knowledge and do not know what to buy and what not to buy , since there are so many boards, shields etc. Also, I live in South Asia, and I will/may have to pay added shipping costs. I want to start and I was wondering if someone could help me out with what I would probably need and what I would not.

Thank in advance.

I accidentally misspelled Arduino in the subject of this post. I am sorry for that.

Any help is much appreciated.

Thanks again in advance.

South Asia, can you be a little more specific?

You can here for distributors local to you as well.

That article was clearly written by a complete idiot. To draw some sensible conclusion about costs, all you need do is get some idea of what you want, make a shopping list, and check it out on eBay.

By virtue of the Arduino's greatest asset, its ability to be expanded and adapted, you may eventually want to do more than you first thought, and this will cost you money. That is entirely your choice, and can hardly be construed as a nasty surprise in the way that that story implies.

I don't see any disadvantage by living in South Asia. Everything you need for Arduino is made in South Asia anyway, and virtually all of it is little bits and pieces that can be bought on eBay routinely quoted post-free. So there's a nice surprise for you.......

If you need help compiling the shopping list, this forum is a good place to find it, but you have to tell us what you want to do.

That article is like buying a car and then complaining that the garage you want to put it in costs more than the car itself and you still have to buy the fuel.

And what is so unreasonable about wanting to know the bottom line?

And what is so unreasonable about wanting to know the bottom line?

An RPI is a small cheap computer without any peripherals. Anyone who buys it without realising that it does not include peripherals such as keyboard and monitor is a fool. Anyone who then complains about the cost of the peripherals they didn't buy is IMO an idiot.

It's like me buying an Arduino clone for $5 and then complaining that I spent a thousand bucks on the computer to program it.

PeterH,
I would really like to know how are you managing anything in your life since you seems to have plenty of opinions, nothing wrong with that, but CANNOT just give a simple straight answer without giving a sermon about it?

HOW MUCH DID YOU PAY FOR YOUR ARDUINO SETUP?

So far I have spend directly about $25 US - for Uno and AD9850 DDS module and 8 channel relay module. .
But I am retired and have been in electronics since 5th grade.

My answer = less than $100 US, including basic tools.

PeterH - your turn...

The question is so vague as to be meaningless. To get started, I bought a UNO. I already had a suitable USB cable. Does that constitute my setup costs? Subsequently I bought another UNO, several shields for various projects, quite a few clones of various types, adapter boards, tranceivers, power supplies, mechanical actuators and sensors and so on. But I would not consider any of this as necessary for a beginner to get involved and I don't know what an "Arduino setup" means. Does it include fab, assembly and test equipment? Patch cables and breadboards and connectors and discrete electronic components so on? Does it include stuff I already had but found useful working on Arduino based projects? Stuff I bought specifically because I needed them for Arduino projects but were useful for other things too? I happen to use Arduinos in some things I do. I didn't buy "a setup", I bought (and still buy) stuff as and when I need or want it, according to what I'm trying to do. That doesn't mean somebody else using an Arduino needs all the same stuff I have. What they need is whatever they need to complete their first project that they don't already have. So, the entry level cost would be the cheapest Arduino compatible microcontroller that is available - a couple of bucks. Beyond that, you spend whatever you want according to your budget and your needs.

Asking the actual costs is like asking "how long is a string"?

Answer: It depends. :slight_smile:

$7 will get you a Chinese "clone" but what kind of project are you building -- RF modules, motor drivers, etc are additional costs but not every project needs them. If you're just playing around learning to blink lights then a handful of 20¢ LEDs might be all you need. But, then you probably want a breadboard/proto shield to plug them in to... and some jumper wires to connect them with... then you'll think of something else you want to do...

So, yeah, Arduino is a lot like a Pi -- you'll end up buying some more "stuff" but it's hard to predict what stuff you'll need without knowing your desired end result.

There are comprehensive Arduino "kits" but then you end up with a pile of stuff, half of which you'll never use.

About $300, because I bought a few boards from various vendors, a few shields, some electronic parts, prototype shields, relays, specialized sensors. But I am evaluating the costs and feasibility of an industrial project.I would say less than $100 if it's for your leisure.

Then, you will want more...

That's not a problem. Go back to your original posting as you read this, select "modify" and just correct it.

The opinion piece you cite is correct in some observations, but misses the mark in general. The Pi was never intended to be the first computer in a household but rather, an educational workstation, though it has a huge variety of variant uses. The concept of it sitting in a student's bedroom, interfaced to the TV she already has (because they all now have HDMI interfaces) using mouse and keyboard cast off by the cycle of PC replacement, powered by her phone charger (since the Pi design chose the EU standard for phone chargers) and connected to the home router, is completely valid, as is the expectation that it may commute to a school laboratory where similar facilities are provided.

In a school situation, all the peripherals are already provided as a requisite, if necessary "borrowed" from a standard workstation for the (limited) duration of use of the Pi. Either the facilities exist or they do not.

But for home use, the peripherals essentially represent "recycling". Last Saturday my foraging at "garage sales" netted for $5 a perfectly functional 22 inch monitor with DVI input (adapts to HDMI) which needless to say, is not immediately going to be used with a Pi (it's now on my wife's computer) whilst an HDMI cable cost $3.50 at Aldi (they come in stock, later they go out at half price). I pay no more than $1 for mice or keyboards at garage sales, a longer Ethernet cable might cost a couple of dollars. Plug packs ("Wall warts"), or USB hubs with a plug pack attached (as you need for the Pi) and USB cables various, generally $1. OK, I have this "thing" for garage sales and not everyone would necessarily spend the time, but I think the point is valid. Not to mention that many of these things are available "dirt cheap" from South Asia (or North Asia with minimal postage - or do they discriminate against their neighbours?).

Probably the most serious limitation of the Pi is that it only has two USB ports; the PcDuino has the advantage here with a third to facilitate a WiFi dongle and in one form, a couple of GB of internal storage.

me on the other hand, for my first foray after finding out about Arduino, I spent about NZ$110 for a experimenters "kit" that contained the yourduino board as well as various componants such as a 2-relay driver board (with relays), various wires led's etc. Down here in New Zealand prices tend to be more expensive (after factoring in exchange rates) than in larger markets such as the USA. I then brought an LCD shield for about NZ$40 and a prototyping terminal shield for about NZ$20. Probably an expensive way to go but at Jaycar electronics here in Wellington an Arduino microporcessor board sells for fron NZ$50 upwards depending on model. I've also added a 4-relay relay driver board for just under NZ$20 whereas the relays themselves for a few bucks from a bargin bin at the electrical wholesalers we get the light bulbs from for the building I work in.

The tools I allready had laying around (although I may replace my soldering iron soon as I've just seen a project in a book I want to make next (arduino/pc based oscilliscope as can't afford a "real" one).
Also I'm having to learn the programming - I've been examining sample scripts that had a line(s) that do things I need and bolting them frankenstein like (but with more thought than frankenstein's monster was built with) and having to do considerable debugging as a result. The time learning is also a "cost" although not directly a monetary one.

In case your wondering, My project is a studio monobloc flash unit driver that lets me plug 4 units in and sequentially fire them, or fire a single one. I allready have the lighting equipment which i use in creating photography/photoshop based artworks.

Another cost can be if you buy physical books.

So from the replies you've had, you can see the "setup" cost can vary from beginner to beginner.

Hey

Thank you for replying.

@CrossRoads; Thanks for the link, that helps a lot.

I do not have any one project in mind. I found many books on Amazon. My course of Computer Science, is Computer Science and Mathematics (minor).

A lot of the Computer Science courses teach students Electronics (Digital Electronics) and Physics as well. This equips the student with the skills they require for industry. So i'm planning on teaching myself and starting learning Electronics through the following books ; Amazon.com
http://www.amazon.co.uk/Hacking-Electronics-Illustrated-Makers-Hobbyists/dp/0071802363/ref=pd_sim_b_13
http://www.amazon.com/Make-Electronics-Discovery-Charles-Platt/dp/0596153740/ref=sr_1_1?s=books&ie=UTF8&qid=1384622257&sr=1-1&keywords=make+electronics

I came across Arduino, while I was searching concerning the Pi, since that too is taught. In many Computer Science courses many students are taught to progamme the Pi as well. I actually first came across garagelab and then Arduino.

In terms of a shopping list I am thinking of starting with an electronics kit, and then adding on the board/s and the LCD. I can not hack an LCD, and I was wondering if anyone has tried and how difficult it is. The LCD isn't that expensive, so either way.
In India, electronics and these tiny parts/components, such as LEDs and cables are really very inexpensive. USB cables really do not cost 5 dollars. In 5 dollars usually you can buy 3 or so, and maybe even a couple more USB cables, depending on the quality. I probably also have a cable lying around.

Could someone please tell me if this is a good way to go about things i.e. invest in an electronics kits first and then add on the Arduino board. By kits I mean, http://www.amazon.co.uk/Electronics-Projects-Starter-Kit-Breadboard/dp/B008WM7UEM/ref=sr_1_3?ie=UTF8&qid=1384623967&sr=8-3&keywords=electronic+kits , http://www.amazon.co.uk/Minty-Geek-Electronics-Lab-101/dp/B005IWMZ4Y/ref=sr_1_2?ie=UTF8&qid=1384623967&sr=8-2&keywords=electronic+kits , but I will not be buying these kits, but assembling them from local or other sources, if it costs me less. The Arduino starters kit is out of my budget.

I had another question, concerning the Arduino boards. I was wondering what kind of knowledge base and experience and skill would be required to make the boards yourself. Electronics/engineering over two years usually leads to a diploma, while three years leads to a degree, with some kind of project work being carried out in the fourth year.
What I'm asking is what level of technical knowledge and unerstanding is needed to copy from the diagrams (schematics?) and if anyone has started out with the boards and went onto learn how to soldier their own and didn't require to do diploma studies to do so? tylernt mentioned $7 clones.
Is there any real difference between thee clones and the (original) Arduino boards?

Also, I had read this article, Why do you hate the Arduino? – Dangerous Prototypes , which assumes every person to be an electronics engineer.

As you don't yet have a project in mind, I suggest the first thing to do is get at least a vague idea. Getting a kit is probably a mistake as it is a sure way of buying stuff you don't want, and you are better off paying for stuff you do want. The best way of getting a kit is when somebody who has no idea of what you need gives you one for your birthday.

Getting a paper library is probably also a mistake and anybody in the game can point to a swag of books that have only been opened once. They all cost $50 and go out of date when the ink dries. The internet is more up-to-date and involves fewer trees.

There isn't much point in hacking an LCD when you can get one for $1 that doesn't need hacking.

Some versions of Arduino, particularly the little ones, are probably best used as modules incorporated into your own board. The standard Uno is a "development board" and the microprocessor can be removed and put into your board after the "development" is done, and yes, you can afford to make a mistake. I don't see the point in trying to copy the circuits, the information is already in the public domain and is almost certainly not going to be what you want anyway.

Arduino voluntarily put their design into the public domain. There is no reason to believe there is any difference between an original and a clone unless it is immediately obvious by casually looking at it. While the Italians have a reputation for design, they don't really have a great reputation for manufacture, and a clone could actually be superior as well as cheaper. The vital components in a kosher Arduino very likely come from South Asia.

I submit the article you quoted in your last has about the same value as the one you quoted in the first, and you shouldn't worry about that sort of stuff.

Thank you again for replying.

What I had meant in my earlier post was, Arduino Breadboard Tutorial -Arduino Workshop Project Video #1 - YouTube . What do you mean by it being a development board and being able to use the microprocessor on my own board?

I was thinking that I could start here , Arduino LED Matrix testing - spiral pattern speed tests - YouTube , with a L.E.D matrix.

I could post links to projects but none of them are beginners projects, or cost effective, or anything that I could/should start with.

http://www.youtube.com/user/appliedplatonics/videos

I'm just going to start with an electonics kit, and I think I'm just in a hurry and being impatient. I'm just going to start and try doing things with a breadboard and try and understand, otherwise I'll come back and post my questions here. Again, thanks a lot for replying/replies.

bomberdoom,
Here is a link to an on line shop that has great prices for components.
I've used these guys many times for things like
resistors, caps, leds, crystals, shift registers, RTC chips, temperature sensors, buttons, etc...
http://www.taydaelectronics.com/

They have MAX7219 chips for $1.25 which are great for controlling a 8x8 LED matrix.

For breadboarding, I think the UNO form factor is not very friendly.
I prefer form factors like Nano, Micro, or the Teensy boards:
http://www.pjrc.com/teensy/
which can be directly plugged into a breadboard.

Yes. As I understand it: get everything right using a Uno, and then fish the chip out and use it in something of your own. I'm not sure why you would actually want to do this. Further, while breadboards are a good idea, I think you should should view them as an adjunct to a Uno rather than a substitute, if only because the Uno is cheap, convenient, and solves the power and communication issues.
