What Is Arduino And Why You Should Know About It

What is Arduino: How to master Arduino Shields

If you are a big fan of electronics like us, are always interested in experimenting and building great projects it’s time you have known about the powers of Arduino.

So read on and explore this wonderful piece of technology with which you can develop simple to the most complex of projects with ease.

What Is Arduino?

Arduino is a popular open-source tool, specifically a development board containing a microcontroller which can be programmed and then acts similar to a computer.

But this computer is not the same as our PCs, it can sense, control and interact more with the physical world. The best part is it’s so easy to program and requires no external hardware to do any of that.

The other important fact that makes Arduino more useful for beginners is the fact that it’s completely open source. Both the hardware and software schematics are available online without any restrictions.

This means beginners can start off well learning from various pre-existing projects and code libraries and since you can build it from scratch, the technology is more transparent than its competitors.

But, remember that building it from scratch isn’t what you should do; mainly because you wouldn’t be able to upgrade it at a later point. And it hurts the purpose of this device in the long term.

Getting Started Is So Easy     

All you have to do is purchase the latest Arduino from their official site or from some place else (online or offline), it costs you around $50. Then download the open-source software from the Arduino site.

Run it on your Mac OS X, Windows or Linux operating systems and the process goes nice and easy.  Now if you are a beginner in dealing with hardware projects, go through the example programs, or “Sketches”, available in the Sketchbook.

These sketches are preloaded into the software and you don’t have to run around the Internet for them.

Here you can get very well accustomed to the Wiring language, on which the entire Arduino language is based on.

After going through few of these tutorials its time you connected the board to your computer via USB port. Follow the instructions and compile the code.

Once you have sent this code to the board, your first experience with the board is done. Now based on the project you want to experiment on, get the right hardware and good code and that’s it. You’re done.

Now that you have the basics intact, you can use Arduino boards for a wide variety of purposes. You can take inputs from multiple sensors and switches and control motors, LEDs and other compatible physical components.

If you are looking to purchase one right now, these link will take you there:

1. Arduino UNO R3 Development Board
2. Arduino Mega 2560 Development Board

Shields Add More Power

Many a time, with the size of your project you may need to interact with more inputs and control more devices than a single Arduino board can handle. This issue can be solved by connecting Arduinos together but the best choice would be to get a shield.

A shield is another board that sits on top of your Arduino and provides extensibility and added functionality into your projects. There are a range of Shields available and you can find them here.

Your Thoughts

How have your experiences been so far with Arduino boards? Do share with us some of your experiences and suggestions. We love feedback!

Silver Is The IDE To Run Apple’s Swift On Windows

Silver IDE

It’s been over an year now since Apple’s new programming language Swift is released. This language got amazing response from the developer’s community and all the statistics proved this. Though Swift is announced to be open sourced by this fall, there are not many tools available till date to enjoy the flavour of this superb language. And most of those tools run only on a Mac. For a developer or for a beginner who’s interested to build native iOS apps, that’s fine but for everyone else it may not be so.

 

With this problem in hand, the RemObjects Software group has developed ‘Silver’, an implementation of Swift programming language. Silver allows you to run write and compile Swift code to develop .NET, Java, Android and Cocoa based apps on Windows as well. It’s not just a compiler like several other web based swift compilers, but is a complete development environment for developing apps.

 

Developers working on Windows can use the power of the Microsoft’s state-of-the-art Visual Studio IDE into which Silver gets completely integrated. In the Visual Studio IDE, Silver acts as a Swift language option and is included into the existing code editor. It extends Swift code capabilities three-fold with additional tooling. With Silver, developers can integrate and deploy apps supported by Android devices, iOS devices and Mac OS X machines. It also provides debugging support for Android, Java and native Cocoa.

 

As RemObjects Software group’s website mentions there is lot more about Silver than just this. Their Elements compiler has the ability to support two more programming languages other than Apple’s Swift. These are RemObjects C# and Oxygene. All these languages have their own uniqueness and the best part is you can include all three languages within the same project.

Silver IDE

Silver also brings with it the oxidiser option with which you can convert code from any of the popular languages into Swift. This option isn’t free for now but truly is worth paying for. For Mac developers Silver is available on the name of Fire, which is a lightweight development environment which is more productive.

 

Learn more about Silver or download it from their official website.

What Is Node-RED Doing For The Internet Of Things Concept

IBM Node-RED

Node-RED is a visual programming interface tailor-made for the Internet of things concept. It requires almost no or little coding experience, and makes it easy to connect physical things to the cloud. This IBM emerging technology takes mankind one step closer in hacking the world as per our needs; providing tools to make this process a lot less cumbersome.

The Internet of Things, is currently at the early stages of its large scale implementation. With Node-RED more developers, even those with less coding expertise can contribute to the growth of this field.

What is Node-RED?

Node-RED is an event managing and handling tool based on Node.js. The Node-RED application, usually runs as a web server, and users can customise and manipulate the interconnections between various hardware and create functional flows from any computer’s browser. No expensive or memory drenching software, it is simple and runs in your web browser itself. This  server application also has the capability to run on devices like the Raspberry Pi.

This entire functionality of the Node-RED is that, you no longer need to enter all the code (at least most of the time) and work with pre contained code. The user interface of Node-RED looks so simple and revealing, you’d hardly have any problems in developing your IoT project with it. Node-RED flows in GitHub actually are represented in JSON (JavaScript Object Notation) and can be easily exported to the clipboard or can be imported into Node-RED or shared online.

Though Node-RED doesn’t completely replace the need to write code altogether, but it significantly reduces it.  In this process the best part is that developers can now concentrate more on building great apps rather than writing same old code repeatedly, which kills creativity.

The fact that Node-RED is open source allows developers to add back to the society. With more and more nodes being added, complex tasks become more simplified and are converted to a matter of drag-and-drop.  It’s such an ecosystem which can extend to several other fields with newer tools being built on top of it. If you are looking to work on a project related to IoT, do check out the prowess of the team behind Node-RED without fail.

WhoCrashed: Discover What Is Causing Your Computer To Crash

WhoCrashed: Discover What Is Causing Your Computer To Crash Or Show A Blue Screen

WhoCrashed is a tool that allows you to analyze errors which caused your computer to restart, shutdown, hang up, or show a BSOD.

This post is for all those who use Windows (usually quite a few people) and have suffered sudden crashes or blue screen (less common things than people think) and want to find out for themselves what caused the problem and whether it is possible to fix their PCs without pulling away or call a technician.

WhoCrashed: Discover What Is Causing Your Computer To Crash Or Show A Blue Screen

In OnlineCmag, every day we talk about something new, and thanks to the blue screen of my laptop which helped me learn of the great tool WhoCrashed.

Who Crashed it ?

WhoCrashed is a tool that parses the Crash file Dump and reveals who or what is causing the ruin of your computer. Sometimes when Windows restarts it suddenly hangs, or throws you a blue screen of death, no obvious apparent reason, without notice, without proper error report, nor any clue, the first thought in anyone experiencing it is that it is some fault in the hardware. But it isn’t exactly true, blue screens are almost always caused by incompatible drivers or by any miscellaneous new software. Fact is that the driver malfunctioning is the number one threat, and Windows 8 / 8.1 seems to suffer from this way more than Windows 7.

The answer in a click…

If the faults are caused by drivers or defective kernel modules, you will only see a blue screen if the computer is configured to show, but what happens is that the PC is restarted just as if possessed by some devil. Instead of calling the Warren you can use WhoCrashed to find out what is the cause of failure.

WhoCrashed shows the failed drivers you have on your computer, and even you can check out the drivers that have caused damage in the past. WhoCrashed performs a “post-mortem analysis” of crashdump and organizes information in an understandable way.

WhoCrashed enabled crashdumps :

The crashdump is a file that is generated after the computer experiences a crash, a spontaneous reboot, or blue screen. The directory of crashdump is: C:\Windows\Minidump and by default they are not active on your PC.

WhoCrashed: Discover What Is Causing Your Computer To Crash Or Show A Blue Screen

To enable crash dumps in Windows go to Control Panel> System and Security> System> Advanced System Settings> Select the Advanced tab and press Settings in the Startup and Recovery section. Now in the table options mark all boxes under Fault system. For best results select a complete dump.

WhoCrashed can cause a controlled crash of your PC to test whether the crashdump works. If you had already enabled, you only have to start analyzing and receiving the responses.

If at all you really want to test this tool before using it, you can check out and use any of top three methods to crash a computer here and get their crash reports.

 

Finally, WhoCrashed is primarily aimed at intermediate and advanced users, system administrators, power users , and not for newbies. This program tells you what is causing the problem, but does not give you the solution, for it, one must understand the report and continue the quest of problem solving.

Getting To Know The Windows Military Grade BitLocker Tool Better

BitLocker: Windows Military grade protection tool

For sure, 2014, has been tiresome and shocking for the entire computer security world. With a whole new range of vulnerabilities surfacing up and some major bug fixes throughout the year, this year really went exciting enough. If at all you missed any of this, catch more of the biggest security stories of 2014 here.

One of these biggest security pieces is the end of services by TrueCrypt. In May 2014, the creators of TrueCrypt ended the services offered by the popular encryption tool. This decision was based on several security concerns and some licensing issues playing their part. TrueCrypt was anyways humble enough to recommend its users to look for alternative solutions. BitLocker, undoubtedly is a the perfect alternative as it can get and here’s our take on this Microsoft’s Encryption Tool.

 

Understanding What BitLocker Is All About:

BitLocker is Microsoft’s encryption tool for Windows. Not all Windows Operating Systems have BitLocker in them, but you don’t have to worry if you’re running on the Enterprise editions of Vista, Windows 7 and Windows 8 or the Pro version of Windows 8.1. All these Operating Systems including few Windows Servers support BitLocker.

The main thing about BitLocker is it helps you pile on additional security to your data with encryption. BitLocker, being a drive encryption tool means that it makes all the data on your drive unreadable for everyone except you. Thus offering you the best protection in case of offline attacks.

Here protection against offline attacks is applicable in case of USB drives, wherein the entire data can be encrypted. So, even if you were to lose your USB drive (or say gets stolen), there’s no harm in it. And the other person surely cannot read what’s inside the drive.

 

The System Requirements:

For BitLocker to run, you’ll need to have any one of the above mentioned Operating Systems. Also the minimum number of drive partitions should be two. So that you can make sure you aren’t encrypting the systems volume, i.e. from where your computer boots. Because it would only make the booting process more tedious if encrypted.

The other main requirement is the TPM (Trusted Platform Module). If you know what is TPM is you can skip the next section. If not, then we recommend you to go through the next section as well.

And in any case you are dubious if your computer matches the above criteria, there’s nothing you’ll have to worry about. Once you run BitLocker, it will run a system check just to check if it can operate on your computer.

 

Trusted Platform Module (TPM):

TPM is a hardware module present on all of those motherboards manufactured after 2006. It is a chip which carefully monitors the booting process, just to make sure there’s nothing messing with it, in order to get around the encryption.

However, the functioning of a TPM is not fixed. Based on your choice, the TPM may ask for a PIN before the OS loads or you may use a particular USB drive as a key to log onto your computer. Or you could do both, however you set it, the TPM monitors the sequence of operations according to your consent.

 

Why Should Anyone Use BitLocker?

If you are concerned about your data theft or privacy, then believe me, BitLocker is the best tool you are going to get; that too with purchasing a computer. Actually, this is a military grade tool which is developed keeping in mind how digital our lives have become. And surely we believe its one of the best of what Windows could offer us.

Do you like the idea of BitLocker? Are you currently using BitLocker? Do you have any other doubts about this tool? Talk all about it in the comments sections. Let people hear you out.
