Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.

Over the years Arduino has been the brain of thousands of projects, from everyday objects to complex scientific instruments. A worldwide community of makers - students, hobbyists, artists, programmers, and professionals - has gathered around this open-source platform, their contributions have added up to an incredible amount of accessible knowledge that can be of great help to novices and experts alike.

Arduino was born at the Ivrea Interaction Design Institute as an easy tool for fast prototyping, aimed at students without a background in electronics and programming. As soon as it reached a wider community, the Arduino board started changing to adapt to new needs and challenges, differentiating its offer from simple 8-bit boards to products for IoT applications, wearable, 3D printing, and embedded environments. All Arduino boards are completely open-source, empowering users to build them independently and eventually adapt them to their particular needs. The software, too, is open-source, and it is growing through the contributions of users worldwide.

Internet Safety: How to Protect Yourself Against Hackers

Recent reports estimate that there will be between 20 and 30 billion Internet-connected devices by 2020. Many people are familiar with computers, tablets, smartphones, and wireless Internet. Now other “smart” devices, like televisions, home security cameras, and even refrigerators, connect to the Internet. More devices mean more avenues for attack by hackers.

What is Hacking?

Hackers illegally access devices or websites to steal peoples’ personal information, which they use to commit the crimes like theft. Many people shop, bank, and pay bills online. People also store financial information, like credit card or bank account numbers, on their devices. A hacker can do a lot of damage even if only one account or device is compromised. To make matters worse, hackers are difficult to stop because they are often located outside the United States and use cutting edge technology to evade law enforcement and acquire large amounts of information.

There are two main ways hackers may try to get your personal information. One way is to try to obtain information directly from an Internet-connected device by installing spyware, which sends information from your device to others without your knowledge or consent. Hackers may install spyware by tricking you into opening spam email, or into “clicking” on attachments, images, and links in email messages, instant messages, and pop-up messages. Hackers use spyware to track keystrokes or acquire pictures of your device’s screen in the hope of snagging account numbers, passwords, and other sensitive information. Criminals can also hack individual websites—like email, social media, or financial institutions—and steal the information stored there.

While trying to protect all your devices and accounts from these criminals may seem daunting, there are some easy, practical steps you can take to keep your information more secure.
