Templates are here for the Oplà IoT Kit. This is a new feature that takes you from unboxing your kit to uploading a sketch and getting a project up and running in record time. And you can do the whole thing without needing any coding.

Arduino Cloud Templates for Oplà IoT Kit
Arduino Cloud is all about ease and simplicity. So it’s been no small task in the background, creating a way to import dashboards, sketches, things and variables that get projects up and running in just a few clicks.

This project was born out of the uncertain times presented by COVID-19. Across the world, many teams that normally were centralized daily to a work location suddenly found them themselves working remotely. The first to be displaced to work remotely from their homes were due to child care facilities being closed.

Hi, in this tutorial we will see how to control electrical devices like fan, light, etc., to turn on and off using esp8266 from a web browser. if you are bored with a dedicated device controller like an app or an remote which will be available for only one particular device but using this method all the device which support web browsing will be act as a  controller for us.

Make sure all the devices are connected to the same router, this example doesn't include a port forwarding function which will not allow us to control the device from outside the home network. 

Components that you need for completing this project are very simple, you need to have an esp8266 wifi module and a relay, make sure you buying a 5v relay which very easy to use with esp chips doesn't require external supply too. we can make use of the Vin pin of the nodemcu or if you are using a generic chip, you need to supply an external 5v to the relay.

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.

The Arduino MKR FOX 1200 board provides a practical and cost effective solution to adding Sigfox connectivity to projects requiring low power. This open source board can be connected to Arduino Create for programming, and to the existing Sigfox infrastructure with it’s broad Europe-wide coverage for collecting data. Sigfox infrastructure runs 24/7 without you needing to do anything to maintain it, and you can always check its status here. The MKR FOX 1200, gives you a great out-of-the-box experience when building IoT projects of any size: from the single sensor monitoring temperature in your home, to an industrial deployment covering the whole of an outdoors factory.

The board's main processor is a low power Arm® Cortex®-M0 32-bit SAMD21, like in the other boards within the Arduino MKR family. The Sigfox connectivity is performed with a module from Microchip®, the Smart RF ATA8520, a low power chipset operating in the 868 MHz range. No extra crypto chip is needed in this case, since the Sigfox network offers its own end-to-end security. These features make it a great IoT node and building block for low power wide area IoT devices within the Sigfox infrastructure.

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.
