It sounds like you felt irked by some of the responses given, would I be right?

You certainly put a lot more thought into justifying yourself where your time spent may have been better used in describing more precisely what you have and what you wish to do in your initial post. Would that be a fair comment?

It is ok to say you are not a technician or a geek or that you don't have certain skills with electronics, though maybe next time say this at the start. Doing so, gives us a way to relate to your skills and I'm sure most of us can relate to this and we can then be more kind, or at least appear so. That said, I do agree with others in that with over two hundred posts here in Arduino land, one would think you may have the skill of doing a little searching with al la google.

Your LED should have some numbers on it I suspect, does it?
If yes, I bet you can google that number with the wording of 'seven segment LED' or even just 'LED' followed by number. If it has a number, did you try that at all?

If the LED you have has no numbers or identification and it was part of some kit or pack you bought then I would seriously suggest you put it in the spare parts box for another day and buy a kit from somewhere else where they do give you the instructions you are needing. Would that seem reasonable to you?

With no identification markings, we are not really able to offer much help to you, and as Rob mentioned, you may just need to firstly allocate a block of time to sit down and work it out yourself with a resistor and suitable power supply.

Most of us have been here for a while now, myself included, and well, we like to talk in detail and with specifics and with some degree of clarity. I hope you would you be willing to try this next time.
They think our disorder comes from excessive late night programming, where you really do need to be careful with your details and being clear, else you end up with what some call a rats nest of a program or circuit that lets the good smoke out too easily.

Stick with it, you'll get there, but don't try to make it extra hard for yourself with a kit with no instructions.
32  Products / Arduino Due / Re: Arduino Due or Beaglebone Black on: February 23, 2014, 03:36:18 pm
You might like to look at using a Cubieboard, rather than a RPi or BBB

I bought a Cubieboard2, which has a dual core A7 with 4GB of NAND and a full 1GB of RAM.
I'm in the process of making a panel that has the Cubieboard2 connected to a DUE for a new renewable energy SCADA system for my home setup.

As you may know, the Arduino range of boards are great for all your IO tasks, so reading and smoothing of analogues and detecting interrupts and setting digital outputs and so forth.

A small Linux based board is great for doing the higher level application based tasks.
I'll be using the Cubieboard2 to be either a Nodejs or Python based real-time TCP/IP server, and have it set up with Debian headless with Nodejs currently for tests.

You can elect to install headless or have HDMI video with a desktop based operating system.
The Cubieboard2 I think has some nice features and looks to be well thought out and designed.

It seems to be amazingly energy efficient as I have it currently on the test bench, where I have the Cubieboard and 80GB SATA drive running Cubian headless all powered via a USB port from another laptop.
As a dual core 1GHz system, this has got be one of the lowest energy consumption systems about.
For use on renewable energy systems, this appears to be close to perfect.

Separating the two tasks and having each system configured to do specific tasks best suited for each board has been a idea I have had for a while now.

I initially researched the various Linux boards and found the Cubieboard2 to be ideally suited to what I need.
It is not unlike the BBB, in terms of physical size and sits well next to the DUE.

Hope this helps.

It looks good to me, running Firefox.
I see menu and files, all 16 of them, is that correct?

Mind you, I am logged into Google, so could that be a reason some others don't see the files.

It is, I use it on both OSX and Linux.

My Eclipse setup on OSX I set up the long method, whereby I setup the Eclipse IDE and then I included the Arduino pluging from Jantje.

For the linux laptop, I simply downloaded a single package from Jantje's site that has everything already setup and ready to go. It really couldn't be any simpler.

There are pakages there for all three major platforms, so take your pick and download.
I would encourage you to take a look at Jantje's site
Then simply head to the nightly builds and select your preference.

For me, the standard Arduino IDE was great to play around with for basic projects, and soon was looking for an IDE that would suit my needs to handle more complex setups.
As well, on my Mac, I usually have two windows open at the same time, one for my current Arduino project and another for HTML/JS/PHP things. I have found it to be very competent at doing all I need.

Let us know what you think.

Yeah and C++ is a ripoff from Java.
I'm not sure that is the case, in fact isn't it sort of the other away around, from what I understand.
Still, if her name is Java, I not complain, imagine Java, Arduino compatible  smiley-lol

P.S. I stand to correct myself, you are correct, oops

You know there's an Australian government conspiracy going on with that.
Until they can abide by the plain packaging laws, no Ardiuno compatible cigar.. or what ever you call them are allowed in the open. Especially with total fire bans in place, you'd need the Arduino fire brigade to leave their sleepy desks.

Man, how did this all start anyhow, Rob, just be happy you can get a ZIF socket to comply to the tight standards that Arduino products have, eer or not.   smiley-grin

Is there anyone interested in a pre Arduino ZIF socket I have, they must be rare as hens teeth then I reckon?
37  Community / Bar Sport / Re: Arduino compatible ZIF socket, WTF? on: January 31, 2014, 10:00:53 pm
You clever bunch you.
I guess a bit every now and then would be great, as long as she doesn't byte during setup() or we'll be having a words in the main loop()
38  Using Arduino / Project Guidance / Re: Much Needed help for final year project. on: January 31, 2014, 05:31:18 pm
Just a quick thought on an idea for what you mentioned in your first post;
would contract and expand as air is blown
THe idea of a small bellow pump, where you use a atandard servo motor to control the bellow action.
The bellow has an inlet valve as per normal and you simply attach an air bladder to the output end to get your contraction and expansion action.
you can use another small servo at the junction of the bellows to air bladder to control air release.
This system will give you an air sound quite similar to human breathing if that is what you are after.
Using a bellow type pump will avoid the noise of any standard air pump, whether displacement or rotational fan.
You might well be able to construct the bellows your self to a shape and size to fit your project.

No, I didn't need to at all, but in doing so I am hoping it will help you.
I did take the time to check and ponder over what you are trying, and then spent time letting you know in an honest way.
I will assume others who look at your post and web site will think the same, and not let you know.

I'm guessing you are upset at how you read my post, and I am sorry if you are, but not sorry for letting you know.
41  Using Arduino / Networking, Protocols, and Devices / Re: Arduino Mega to Micrologix 1400 on: January 30, 2014, 05:59:19 pm
If I were you I would first look at using the DF1 protocol that is available on the Micrologix 1400.
DF1 uses standard RS-232 electrical specification, and I think you may find that that will be an easier approach.
You could also look into the ASCII protocol in your Micrologix 1400 too.

It sounds to me you are unsure of how any of these protocols work on the Micrologix range of PLCs.
Might I suggest you use google to find a wealth of resources on the web.
Here's one I just found

You did not say, but I am assuming you are using a computer with Microsoft windows, right?
And you have RS-Logix500 programming software and also RS-Linx to help setup comms between your RS-Logix500 and Micrologix 1400
Here, this is another site with some useful info

You'll need to become quite familar with the way in which Allen Bradley PLCs do thier serial comms first before you can start to connect up your Arduino.

You will need to understand the differences between the different electrical specifications such as RS-232 RS-485 and things like half or full duplex.

Once you undertsand the serial protocol, you will need to learn how to access the data areas in the Micrologix where you wish to store your data, such as what sort of file type, i.e. N for integer.

Out of curiosity I went to visit your web site, and must admit I have absolutely no idea what you are about.
On the website you mention;
This website is designed to be a resource to the TurtTech Team
Who is this team and what do they do?
You mention R.O.V. and my understanding it that that stands for Remotely Operated Vehicle, is that what your web site is about I wonder?

On your page called 'Common DataSheets' you attempt to display two images, errr, badly, and what would those two images have to do with remotely operated vehicles I wonder.

I'm thinking you need to bring your idea, concept and web site to more that 'full strength' as you say in order to generate interest.

Anyhow, it seems you are excited about whatever it is and all great ideas start with one person I guess, especially with a 'lynix',or do you mean Linux netbook
43  Using Arduino / Networking, Protocols, and Devices / Re: real-time data from arduino sensors to mobile web browser using ethernet shield on: January 13, 2014, 09:27:46 pm
I have another option for you.

I too wanted a fast method to have data from the Arduino to web browser.
So, initiatlly I too used the method most people end up doing, that is, set up your Arduino as a small internet server.
For me, it has limitations in terms of how I wanted to develop a system over time.

Next I made it so that the Arduino simply sent data to my host server using HTTP POST format.
That works and I can store data in my SQL database easily too which I use for trends.
But, again, the problem with this is that it needs regular and continuous POST commands from the Arduino.

So, my next stop was to look at using a publisher/subscriber model.
And what I did then was to make my Arduino routines work such that after I filter the analog values I maintain various flags for each analog. One of them is a 'change of value' or COV bit. That allows me to send the data of any analog only if it has changed in value by a given amount.

So, then I send that data to a site called PubNub, no, it's not your local place of worshipping the liquid amber, it's a site that is set up for using a publisher subscriber model which means the ability to have next to real time data available from a source to a destination.

I did a few rough tests a while back and had notice the time difference I would get between data sent via standard polling methods, where the Arduino sends to host server and client requests from host server, to the method of Arduino sends to PubNub and client is subscribed to your PubNub channel.

With any polling or timed based technique, you will always need to wait the time period of your poll period.
Try to make the poll period faster and you run into problems in other aspects of your system, and you simply end up trying to send loads of data that may be unnecessary.

With a system where you use change of state or value you reduce this unnecessary overhead. Then by using a publisher subscriber model the turn around time from input into the data broker to you getting it as a subscriber is counted in a few hundreds of milliseconds.

When I see a data change on the Arduino by indication of a LED, I will have that data on my browser screen in typically 250mS, regardless of where I am in the world as long as the DSL connection I have is soild.

The upshot is that your browser app is very light weight, no need for AJAX, as used traditionally. Also, your Arduino is not a web server and hence trying to service an unpredictable amount of incoming HTTP requests, rather, it  sends out the data, and only when there is a need. What you have then is very fast data from the sensor to the screen, anywhere in the world and any number of clients. Millions of clients if you wish, with no impact on your little Arduino.

PubNub have APIs for working with many systems, Arduino included.
44  Using Arduino / Programming Questions / Re: Using other IDEs to develop on: January 02, 2014, 05:36:28 pm

I wonder how much better a programmer you could be if you would take the time to read better.

45  Development / Other Software Development / Re: Problem with Eclipse/Jantje Plugin vs Arduino IDE using Arduino DUE on: January 01, 2014, 09:22:48 am
mmm interesting, I wonder if it will also apply to Linux and OSX configurations?
If I get a chance tomorrow, I'll like hook one up and see what happens.
