9 Arduino Projects You Cannot Ignore

Arduino CEO, Massimo Banzi has made some really cool videos of what all you can do with this little piece of hardware.

Arduino can be much more fun than just being an electronic prototyping platform. The fact that it is open source allows you to do various crazy, wacky, yet creative things. For those living in caves, Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists and anyone interested in creating interactive objects or environments. Well, Arduino CEO Massimo Banzi has made some really cool videos of what all you can do with this little piece of hardware. Here we present nine interesting Arduino projects that will make your tryst with this platform even more fun. Check them out.

Spaceship Interface

Within the demonstration, Banzi creates a circuit that shows how easy it is to connect LEDs and buttons to the Arduino board. Banzi even shows us how the Arduino software can interact with the various other components. Specifically, he sets the conditions and variables within the Arduino code that can manipulate the LEDs when certain criteria are met.



The Love-O-Meter

Massimo Banzi shows us how to create the inexplicably named "Love-O-Meter". Quite simply, the system acts as a thermometer, and it is capable of measuring how hot (or not) you are. Banzi also uses several clever pieces of kit, including a temperature sensor that emits a voltage proportionate to every degree of centigrade it detects. Banzi then runs through the code needed to implement this rather curious behaviour.



Light Theremin

This time, Banzi is showing us how to make a light Theremin using the Arduino starter kit. In his simple circuit, Banzi uses a buzzer and a light sensor that will be used to judge the distance of your hand from Arduino. Banzi then hacks the hardware to show users how to change the pitch of the sound in relation to the amount light that the sensor detects. So if you are feeling musical, make sure to check out the latest Arduino video from RS Components. It is a great lesson that will surely help you to get the most from your starter kit!



Keyboard

In this tutorial video, Massimo Banzi explores the possibility of making musical sounds with the Arduino Starter Kit. To do this, Banzi has created simple circuit on the Arduino board, which is then completed with four buttons and a mini piezo speaker. But to make the device resemble a mini keyboard, Banzi has programmed each button to play a different note. Banzi then uses the Arduino software define different frequencies for each note within the code. But don’t worry if this sounds rather complicated, as he goes through the code line-by-line to show us exactly how to make a mini-keyboard. So to start making music, make sure that you watch the latest video.



Twitter-controlled Mood Lamp

This time, Banzi will be using a Wi-Fi shield module to connect his Arduino unit to the Internet. This obviously opens up a whole range of new possibilities, which Banzi explores in the video. For the purposes of this demonstration, Banzi creates a simple lamp circuit that will change colour according to the messages posted on Twitter. So if someone, for instance, Tweets a message that begins with #ArduinoRGB followed by a colour represented by a six digit decimal number (like the way colours are displayed in HTML), the lamp will then change colour accordingly. So to see how this clever device works, make sure that you tune in to the final video.



Motorized Pinwheel

It's time for another instructional video from Massimo Banzi, and this time he's showing us how to make a motorized pinwheel with Arduino. To do this, Banzi will be controlling a DC motor using the Arduino board so that he can spin the wheel at different speeds. However, creating a motorized pinwheel has its own set of unique challenges. For instance, a DC motor works at a higher voltage than the Arduino. This means that it requires more current that an Arduino pin can provide. This is, of course, a difficult problem to overcome, as too much current will burn and destroy the Arduino pin. So how will Banzi overcome this obstacle? Well watch the video to find out...



Crystal Ball (Magic 8-Ball)

Many of us fondly remember having a crystal ball (Magic 8-Ball) in our younger days, but now Massimo Banzi is showing us how to construct one from the materials in the Arduino starter kit. The electronic version of the Magic 8-Ball is completed with a LCD screen and tilt sensor, which will provide the user with a randomly generated answer after the circuit is shaken. If you would like to know how this is done, Banzi also looks at the code to show us how everything works.



Touchy-Feely Lamp

Back with a brand-new Arduino starter kit project, Massimo Banzi walks us through the process of making a touch sensor lamp. Banzi also introduces us to the concept of external libraries for the Arduino. This is an extremely useful tool that should help streamline the development process for beginners and experts alike. Put simply, an external library can be downloaded and installed into the Arduino development environment. They are essentially a database of pre-written code that can be used in your device to programme certain behaviours. In this case, the eternal library enables Banzi to create his touch sensor lamp quickly and efficiently.



Tweak the Arduino Logo

Good news... it's time for another Arduino instructional video with Massimo Banzi! And this time, our favourite Italian hardware hacker will be using the Arduino to control software running on your computer. To do this, Banzi will be hooking the Arduino board up to a computer via a USB connection, and then use a specific programme to change the colour of the Arduino logo. By the end of the video demonstration, you should be able to send a value from Arduino to your computer, and then use a program to interpret this software as a colour. Finally, you will be able to change the colour of the Arduino logo easily using a simple dial.

Hacking is a fascinating field but it definitely isn't easy. Here we have listed 12 of the most important steps essential to become a hacker, together with all the resources that you need for learning.

Here we focus on the skills and attitude needed to become a hacker. Breaking the security system and entering into the system is not the only thing a hacker does. One requires knowledge of a wide variety of subjects and in depth knowledge of programming languages and operating systems. And needless to say, learning is essential in the journey...
Here are the 12 steps:

It is not an easy task to become a hacker. As a hacker, you need to have an attitude and curiosity. Reading the hacking manifesto can teach you the attitude of a hacker. Nurturing the hacker attitude is more about developing competence in the languages rather than having a stereotypical attitude.

Though a lot of people consider that a hacker is a criminal, in real life, they are hired by big companies for protecting information and minimizing potential damage. The act of hacking actually is that of being over-curious and outwitting authority. As a hacker, you should be hell bent on breaching authoritarian rules, secrecy and censorship. Deception is another arsenal which will allow you to dodge the vigilant eyes of authority.

The act of stealing something or doing harm to someone is not hacking. Such people are commonly called crackers in the community. Crackers are involved in illegal activities and we do not recommend you to get involved into such activities.

Step 1: Learn To Program In C

C programming is one of the most powerful languages in computer programming. It is necessary to really master this language. This programming language was invented by Denise Ritchie in between the years 1969 and 1973 at AT&T Bell Labs. C programming will essentially help you divide the task in smaller pieces and these pieces can be expressed by a sequence of commands. Try writing some program on your own by assessing the logic.

Step 2: Learn More Than One Programming Language

When you are trying to become a hacker, it is very important to learn other modern computer programming languages such as JAVA, Perl, PHP and Python. One of the best ways to learn these is by reading books from experts.

Here are 32 free ebooks on JAVA

Here are 24 free ebooks on Perl

Here are 21 free ebooks on PHP

Here are 50 free ebooks on Python

Step 3: Learn UNIX

UNIX is a multi-tasking and multi-user computer operating system that is designed to provide good security to the systems. This operating system was developed by some employees of AT&T in Bell Labs. The best way to learn it is to get into an open-source version (e.g. centos) and install/run the same on your own. You can operate internet without learning UNIX, but it is not possible for you to be an internet hacker without understanding UNIX.

Step 4: Learn More Than One Operating Systems

There are many other operating systems apart from UNIX. Windows operating system is one of the most commonly compromised systems, hence, it is good to learn hacking Microsoft systems, which are closed-source systems.

According to the National Vulnerability Database, Microsoft operating systems have a large number of vulnerabilities.

Windows OS installers are distributed in binary, therefore, it is not easy for you to read the code. Binary code is basically the digital representation of text and data that computer understands. However, knowing how programs are written for Windows and how different applications behave on this operating system will help.

One of the recent vulnerabilities of a popular OS was that Java Web Start applications get launched automatically even if the Java plug-ins are disabled. How to be a hacker is about knowing the weaknesses of these operating systems and targeting them systematically.

Step 5: Learn Networking Concepts

The networking concept needs to be sharp when you want to be a hacker.

Understanding how the networks are created is important, however, you need to know the differences between different types are networks. Having a clear understanding of TCP/IP and UDP protocol is a must to be able to exploit the vulnerabilities on world wide web.

Understand what is subnet, LAN, WAN and VPN.

The networking commands to do a HTTP request needs to be on your fingertips. The HTTP protocol, is the gateway through which one enters the internet world. Hence, it is necessary to learn this protocol in order to break the barriers. The hackers often use the HTTP gateway to breach the security of the system and take control over it.

Apache Httpd is one of the most commonly used web servers and knowing in and out of it is going to empower you on any HTTP or other application layer protocol related endeavors.

Also Nmap is a powerful network scanning tool that is used by hackers and security professional across the world to identify vulnerable hosts. However, to effectively start using it you must understand the networking basics.

Step 6: Start Simple: Go Through Tutorials About Hacking

This is the simple and best way to start. Read as many tutorials as possible that are meant for hacking. These articles will give you insight and help you develop the attitude to be a hacker. Some tutorials will initiate you with Nmap, Nessus and SuperScan, some of the hacking programs or tools that hackers generally use. These tutorials are readily available over the internet; Both text and video tutorials are available for you to answer your question how to be a hacker.

Here are some of the video tutorials

Here are some of the text tutorials

Step 7: Learn Cryptography

As an expert hacker, you need to understand and master the art of cryptography. The technology of cryptography and encryption is very important for internet and networking. It is the practice and study of techniques that are used for secure communication in the presence of third parties. The encryption is done for various aspects of information security such as confidentiality of the data, integrity of the data and authentication. Moreover, the technology of cryptography is extensively used in ATM cards, computer passwords and e-commerce. While hacking, these encrypted codes needs to be broken, which is called decryption.

Understand various techniques used for password cracking. There are dozens of tools available to do password cracking, and using it is not hacking. To be expert at hacking its important for you to understand how to create a program that can crack a password from cypher text.

Step 8: Experiment A Lot

This is an important step for setting yourself up as an expert hacker. Setup a laboratory on your own to experiment the learning on the practical applications. A simplest lab will have your computer, however once you advance you may want to add more and more computers and required hardware for your experiments.

It is good to try experimenting on your own computers, where you can rectify if you have done any mistake. Many hackers initially start off by downloading virtual lab applications such as Oracle VirtualBox. You require at least 3 GBs of RAM and a comparatively powerful processor to carry out your hacking experiments. Setting up the virtual machine is crucial, as it will allow you to test virus, applications and different servers without affecting your own PC.

Some of the things you may need to keep in mind when doing experiments

- Keep a backup before any experiment.
- Start small and have check points.
- Know when to stop.
- Document your progress
- Keep improvising
- Automate repetitive tasks

Step 9: Read Some Good Books From Experts

Reading will always enhance your knowledge. Try to read as many books and articles as possible written by the experts in the field field of ethical hacking and enterprise security

Reading a lot about anything related is so important in the world of hacking that you must also consider enhancing your reading speed. If your reading speed is slow, then you may not be able to progress fast in this field. Practice speed reading techniques like skimming, chunk reading etc.

When it comes to reading a lot, it's also important to know that a majority of content on web is not worth your time. Many people use search engine tricks to attract traffic but have little value in it. If you skim through an article within seconds and decide not to read that is going to save you a lot of time for some really well researched content.

Step 10: Go Next Level: Write Vulnerability

Vulnerability of a program is the weakness of the program. It is a good approach to look for the vulnerability of an existing program and share the same with others. In this way you will have the option to collect varied opinions from different sources, enabling you to hone your current skill set.

The examples of computer vulnerabilities include memory safety violation, input validation error, privilege confusion bugs and user interface failure. For instance, Microsoft’s Internet Explorer 11 had the vulnerability bug in its preview version which several hackers exploited.

Identifying a new weakness in any software is the real work any expert hackers would perform.

Step 11: Contribute To Open Source Security Projects

Contributing to an open-source computer security project is a great platform to test your skills. This is not everyone’s cup of tea. Many organizations like Mozilla and Apache offer these types of open source projects. Try to be a part of these projects and add a valuable contribution to the benefit of the community.

Participating in the open source security projects such as anti-spam, anti-virus, firewall and data removals help you augment your dexterity as a hacker. Contribute your vulnerability findings to the global vulnerability databases and give back to the community.

Remember that it does not matter if your contribution is small, as long as you participate and add value it helps.

Step 12: Continue Learning And Keep Listening To Security Talks

The key to success in the hacking career is continuous learning. Reading blogs for hacking available at sites such as hackerfactor blog and IKEA hacker blog; participating in the forums such as hackforums.net and elite hack are great ways to refresh your knowledge as a hacker. The online video forums like TED or TechTalk are good sources to know more about the emergent hacking techniques and technologies that are being deployed. You should also try following the posts of famous hackers such as Adrian Lamo, Kevin Mitnick, Kevin Poulsen and Robert Tappan Morris.

Happy Hacking
