Have you ever walked into a store knowing what you want to buy, but it took you longer to find the product than driving to the store? Ever wondered why? It's not the store trying to play treasure hunt with you, it's the lack of precise directions in a confined, closed and constantly changing environment.
What we have to say, what you want us to hear.
That’s how our blog works. It’s interactive. Let’s learn together.
If you have been thinking about exploring concepts and projects related to IoT, but have not been able to decide where to jump in, this blog post is for you! While there are dozens of online courses, many of those fail to provide hands on experience that can resonate and help you understand some of the concepts involved in IoT. So with that in mind, here are three avenues you can explore IoT with varying levels of cost, time, and hardware involved.
Once you have an idea for a mobile application, it can be difficult to choose a development platform. There seems to be a never ending list of options, with new ones added daily. Asking around for advice can make the decision more difficult, as everyone tends to have their own preference or bias for using one platform over another.
As has been mentioned in past blog posts, there are security concerns with IoT systems. When discussing distributed ledger technology (DLT) we investigated how a blockchain approach could address the security concerns, but introduces system demands in terms of memory and computing power that do not appear practical for many of the simple IoT devices on the market today. Enter the permissioned blockchain; a network where only specific nodes are required to maintain the transaction ledger and determine which transactions are allowed. This addresses the problem with strict centralized control discussed in the first blog post in this series and the issue of memory demands discussed with a completely decentralized model in the second blog post.
