Let’s combine the Fishino UNO power with the convenience of Google Home voice assistants, so that we can forget about the remote control and manage various devices with simple phrases. With this project, we are going to exploit the new technological ecosystems that are populating our homes: the voice assistants. In particular, we will see…
Here we go! This is a very programming-heavy project, but I think it has a pretty good reason to be. The Evdev library that we use doesn’t have a lot of resources on reading from analog sticks, so I wanted to focus on that specifically in this tutorial. More info
We are going to use digital signatures to add security to our system. If you want to learn more about how to use the Cryptographic Co-processor, check out this tutorial and video. These will show you the fundamental ideas behind digital signatures, walk you through how to setup each co-processor. For the secure garage door opener example…
Let’s start using our IoT boards based on Arduino architecture. In our previous posts, we presented Antennino, a special Arduino board with connectivity functionalities, capable of operating in Peripheral or Gateway mode. We stopped at the hardware description and configuration, promising to return to the topic to show you an example of use applicable…
Let’s discover how to load the bootloader on our IoT board, so to prepare it for the usage. You learned about Antennino when reading the first part of this article, in which we presented the project and described the hardware, in detail. Let’s resume the discussion from where we stopped, that is to…
A multirole board, that stands out for its very low energy consumption and the possibility to be remotely programmed, emerges in the rich landscape of the IoT modules. When talking about IoT, we usually refer to devices that are powered by batteries and that are scattered in the environment, for the purpose of acquiring and…
Palmtop transmitter to couple with the LoRa Shield to execute longer-range radio commands. Among the longer distance radio transmission technologies with low energy consumption, there was one in particular on which we have focused our attention, it is the one LoRa (Long Range) produced by Semtech (www.semtech.com) with a product based on it, some…
