Securing the Internet of Things | #CyberSecurity #Coding #Arduino #IoT

Securing the Internet of Things | #CyberSecurity #Coding #Arduino #IoT | 21st Century Learning and Teaching | Scoop.it

Aside from cool cat feeders, it is possible to find multiple maker projects for controlling garage doors, blind windows, smart locks, tracking cars, control temperature and humidity levels, and so on. However, the security aspect of these devices needs to take some extra attention, starting from the connection between the device and the Cloud infrastructure.

 

Most microcontrollers today are not powerful enough to handle secure connections, like SSL or TLS, so all the communication between the device and the server is open to attacks, like sniffing values, tacking device credentials, faking values, granting unauthorized access to physical facilities, unlocking doors, and many other possibilities. This way, securing the communications for all the Internet-connected devices should be a priority, especially if they can jeopardize our security or privacy.

The security of the Internet of Things does not only rely on secure communications, but it is a great start. The maker community must be aware of the security concerns of untrusted communications, and must have the appropriate resources to handle it. This way it is common to see different alternatives to offer secure communications in the microcontrollers, like porting SSL/TLS libraries to cheap devices like ESP8266, or device vendors that already integrates a crypto chip that process all this stuff by hardware, like the recent Arduino MKR1000.

In thinger.io we are concerned about this security aspect, so our cloud supports secure connections for any device with this capability. In the recent Arduino library update, starting from version 2.4.1, we have introduced support for the Arduino MKR1000, including secure TLS connections by default. Just start with the following sample sketch for the MKR1000, and you will have encrypted connections by default.

Exchange any data between Blynk app and your hardware.

 

What is Virtual Pins
Exchange any data between Blynk app and your hardware
 

Virtual Pin is a concept invented by Blynk Inc. to provide exchange of any data between hardware and Blynk mobile app. 

Virtual pins are different than  Digital and Analog Input/Output (I/O) pins. They are physical pins on your microcontroller board where you connect sensors and actuators.

 

Blynk lets you control any hardware connected to Digital and Analog pins without having to write any additional code.

For example, if you need to turn On/Off LED connected to Digital pin, you don't have to write any code: 

  1. Just use BlynkBlink code for your hardware
  2. In the Blynk app - add Button Widget and set it to pin D8
  3. That's it! No additional code is required. Simply press Play in the app.

Switch Basics | #Electronics #Maker #MakerED #MakerSpaces

Switch Basics | #Electronics #Maker #MakerED #MakerSpaces | 21st Century Learning and Teaching | Scoop.it

Poles and Throws, Open and Closed
A switch must have at least two terminals, one for the current to (potentially) go in, another to (potentially) come out. That only describes the simplest version of a switch though. More often than not, a switch has more than two pins. So how do all of those terminals line up with the internal workings of the switch? This is where knowing how many poles and throws a switch has is essential.

The number of poles* on a switch defines how many separate circuits the switch can control. So a switch with one pole, can only influence one single circuit. A four-pole switch can separately control four different circuits.

A switch’s throw-count defines how many positions each of the switch’s poles can be connected to. For example, if a switch has two throws, each circuit (pole) in the switch can be connected to one of two terminals.

Knowing how many poles and throws a switch has, it can be more specifically classified. Commonly you’ll see switches defined as “single-pole, single-throw”, “single-pole, double-throw”, “double-pole, double-throw”, which are more often abbreviated down to SPST, SPDT, and DPDT, respectively.

How to buy a registered UK driver's license with documents everywhere
Our company works in partnership with 4 driving schools in England,Northern Ireland,Scotland and Wales where hundreds of driver’s licenses are being issued in England each year. We have realized that some of these cities are too far for some of you to attain the theoretical and practical exams and some people are so busy at work and has no time to attend a driving exams. We enroll you to one of these driving schools and your files are treated like any other file due to our partnership with them.
How to apply for copy certificates
We encourage you to apply for a replacement or copy of a birth, death or marriage certificate directly from the General Register Office and not from the Royal Borough of Greenwich.

Animating Multiple LED Backpacks | Adafruit Learning System

Animating Multiple LED Backpacks | Adafruit Learning System | 21st Century Learning and Teaching | Scoop.it

Adafruit LED backpacks make it incredibly simple to add small bitmapped displays to a project. Each requires just four wires: power, ground and two communication lines to a microcontroller.

Two common questions we receive:


How can I use more than one 8x8 matrix backpack in an Arduino sketch?


Can I have two (or more) matrices always showing the same image?


This tutorial demonstrates both.

We’ve had spooky Halloween displays on the brain lately, but the concepts here are equally applicable to more innocent schemes!

KidBright32 Board is Thailand's BBC Micro:Bit Equivalent | #Coding #Maker #MakerED #MakerSpaces 

KidBright32 Board is Thailand's BBC Micro:Bit Equivalent | #Coding #Maker #MakerED #MakerSpaces  | 21st Century Learning and Teaching | Scoop.it

BBC Micro:Bit board was first announced in July 2015. Designed for STEM education, the board was then offered to UK schools in March 2016, and a few months later UK store would start selling it worldwide. It’s now available pretty much anywhere, and you can likely find it in a local store or online.

The Thai government must have seen this, and thought to themselves “If the British can do it, we can do it too!”, as the National Electronics and Computer Technology Center (NECTEC) part of Thailand’s Ministry of Science and Technology designed KidBright32 board and courses to teach STEM to Thai students.

It’s Time for Grown-Ups to Grow Up | #Character #Moral #ETHICS

It’s Time for Grown-Ups to Grow Up | #Character #Moral #ETHICS | 21st Century Learning and Teaching | Scoop.it

Kids do crazy things, but we expect more from grown-ups, don’t we? Unfortunately, that’s not always the case. Folks scream obscenities at ballgames, bully people on social media, and treat others with total disrespect. If you think this behavior is rude, insensitive, and tasteless, you’re right. But why is it so prevalent? The truth is, some people behave this way for personal gain; some folks don’t know better; and others know they’ll get away with it — because they have in the past. Some grown-ups never grow up.

While some indiscretions were once considered outlandish, we’ve become desensitized to these actions. It’s troubling that some of this behavior could have been avoided, but too many of us didn’t speak up. Instead, we closed our eyes to the poor behavior and waited for others to make the first move. The consequence is that wrongs committed by enough people become the norm over time. We have no one to blame except ourselves.

As leaders, role models, and parents, we must utilize every opportunity to reinforce the values that we hold dear.

What Values Do You Cherish?
Are polite manners a thing of the past? Should people honor their word? Is it Pollyanna to expect people to do what’s right? I think not! But if we don’t promote good values, don’t be surprised when bad ones become the norm. “How do we improve the situation?” you ask.

First, we must modify our criterion of excellence. It’s not what you have but who you are that counts. Moral character matters!
