21st Century Learning and Teaching

From fields and streams to offices, factories, hospitals and transportation systems, organizations are using internet of things (IoT) sensors to collect massive amounts of data in order to improve operations and increase sustainability. 

Analyzing this information reveals patterns that can nip maintenance problems in the bud and lead to better decisions about resource allocation. As data accumulates, more functions can transition over to automation. Systems become smarter, using artificial intelligence to make speedy decisions without human intervention.

First Steps with the NodeMCU ESP8266 Wi-Fi Module. In our previous tutorials we were using already the NodeMCU ESP8266 Wi-Fi Module and we discussed about "Security", "Cyber-Security" issues while using "IoT", "Internet of Things" and the importance that the router MUST be protected by a NEW password and NOT ALLOW to let connect any…

Want to make your project talk to the Internet? Connect your existing project to the Internet to log, stream, and interact with the data it produces? What about all this Internet-of-Things (IoT) stuff?

Adafruit IO is a platform designed (by us!) to display, respond, and interact with your project's data. We also keep your data private (data feeds are private by default) and secure (we will never sell or give this data away to another company) for you. It's the internet of things - for everyone!

Why We Built Adafruit IO
Here at Adafruit, we sell all of these amazing components, but we couldn't find a good way to interact with them over the Internet. There are certainly a lot of great services out there for datalogging, or communicating with your microcontroller over the web, but these services are either too complicated to get started, or they aren't particularly fun to use. So, we decided to experiment with our own system, and that's Adafruit IO.

About this Project:

In this project we will learn how to interfacing ESP8266 module with MAX7219 matrix display to scrolling text message from web user interface. We will use Arduino IDE to program ESP module in this project. I am using MajicDesigns MD_MAX72xx library for running this project, also the code is very similar to included example in the library with some improvements in web user interface html code.

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.

In this new tutorial on Cayenne IoT, we will learn how to control an articulated Pan-Tilt PTZ SG90 system in WiFi. In the previous tutorial, we saw how to do with the Blynk library and application. Cayenne IoT is fairly similar. It is necessary to pass through the servers of myDevices.com which can cause a small delay of latency (quality of Internet connection, server load …).

We continue to bask in the glory of the information technology revolution, now a three-decade-long event, which has reshaping the jobs of professionals and corporate staffs across the globe. However, it seems most workers have actually been left out of the equation -- the so-called firstline workforce, consisting of field technicians, healthcare providers, retail clerks, drivers, and so on.

They're called "firstline" for a reason -- they're the people with whom your customers are most likely to have first and only contact. If they can't deliver the goods or services because they are missing out on technology, then your company is seen as unable to deliver, simple as that.

With the rise of the Internet of Things and associated artificial intelligence, it's more important than ever that firstline workers receive the training, support and technology tools they need to deliver on meeting their customers' needs. Manufacturers, in particular, are seeing a dramatic shift in their business models, with more revenue coming from aftermarket service and support, especially as they develop the ability to monitor products and run analytics for predictive maintenance.

More than 80 percent of executives in a recent survey from Forbes Insights and Microsoft agree that empowering firstline workers with the tools and platforms they need has a direct impact on customer satisfaction, growth and worker job satisfaction,. In this survey, which I helped design and analyze, we found that this important component of the workforce continues to be overlooked.
