Alexa, Please send fifty IOTA’s to Alice
Alexa, What is my IOTA balance?
Alexa, What is the current IOTA transaction throughput?

These are some of the cool things you could teach Alexa to do after completing this tutorial…

Introduction

This is the 20th part in a series of beginner tutorials where we explore integrating physical devices with the IOTA protocol. In this tutorial we will look at integrating the Amazon Alexa virtual assistant with the IOTA protocol. …

Introduction

This is the 19th part in a series of beginner tutorials where we explore integrating physical devices with the IOTA protocol. This is the second part in a two part tutorial where we look at using the IOTA token as the settlement currency in a peer-to-peer energy trading solution. In the first part we focused on monitoring real time power consumption and making payments accordingly. In this second part we will look at dealing with variable energy prices, a common problem that must be addressed when dealing with renewable energy sources such as solar, wind, hydro etc.

Note! If you…

Introduction

This is the 18th part in a series of beginner tutorials where we explore integrating physical devices with the IOTA protocol. This will be a two part tutorial where we look at using the IOTA token as the settlement currency in a peer-to-peer energy trading solution. In the first part we will focus on monitoring real time power consumption and making payments accordingly. In the second part we will look at dealing with variable energy prices.

Note! In this first tutorial the solar panel is optional as we will primarily be focusing on the circuit between the energy provider batteries…

Introduction

This is the 17th part in a series of beginner tutorials where we explore integrating physical devices with the IOTA protocol. In this tutorial we will be creating the basic functions of an IOTA powered reverse vending machine using a Raspberry PI, a touch display, a camera, and a bar-code scanner.

Note!
The touch display and/or bar-code scanner is not required to play around with this tutorial as you also have the option of interacting with the UI using a traditional monitor, mouse and keyboard.

When I started working on this tutorial my initial idea was to do some type…

Introduction

This is the 16th part in a series of beginner tutorials where we explore integrating physical devices with the IOTA protocol. In this tutorial we will be using a bar-code scanner together with our own web app. to simulate using the IOTA tangle to create a tamper proof audit trail of events in a typical supply chain with multiple actors.

Note!
You will also have the option of typing in bar-code ID’s manually in case you don’t already have access to a bar-code scanner.

In my personal opinion, supply chain management is probably one of the first areas where we…

Introduction

This is the 15th part in a series of beginner tutorials where we explore integrating physical devices with the IOTA protocol. As promised in the previous tutorial; this time, instead of integrating our IOTA payment system on top of the proprietary and closed source Phillips Hue system, we will now take the same idea and apply it on top of the open source Zigbee hardware and software platform.

Note!
Notice that the Phillips Hue system is also based on the Zigbee protocol, so any Hue devices that you may already own should work fine with this tutorial.

Note! I suggest…

Introduction

This is the 14th part in a series of beginner tutorials where we explore integrating physical devices with the IOTA protocol. In this tutorial we will be revisiting the use-case from the first tutorial in this series, where we built a simple power circuit that would allow us to purchase services from a physical device using IOTA tokens. In this tutorial, we will take on the same idea and apply it on top of an existing ecosystem of hardware and software, namely the Philips Hue.

This will be a two-part tutorial where in the first tutorial we focus on integrating…

Introduction

This is the 13th part in a series of beginner tutorials where we explore integrating physical devices with the IOTA protocol. If you have been following the IOTA project for some time you may have heard about strange ideas such as “cars having their own wallets” or “cars paying for their own services”. While this may sound intangible and futuristic, it’s basically the idea we will be taking on in this tutorial.

The use case

As you may remember, we ended the previous tutorial by pointing out some problems related to the centralized nature of the ALPR approach, where a centralized entity (aka…

Introduction

This is the 12th part in a series of beginner tutorials where we explore integrating physical devices with the IOTA protocol. This time we will look at simplifying and automating payments for typical car related services such as parking, toll-road, washing etc. using the IOTA protocol.

I decided to make this a two part tutorial as i believe there are multiple ways of approaching this use-case. Each with its own advantages and disadvantages. More about that later.

In this first tutorial we will try to solve the use-case by utilizing a technology commonly referred to as Automatic License Plate Recognition…

Introduction

This is the 11th part in a series of beginner tutorials where we explore integrating physical devices with the IOTA protocol. Its been i while since i published the last tutorial in this series as i have had to make some other priorities. This will change over the next coming months as i now have received donations from the IOTA development fund that will allow me to continue making these tutorials.

While on the topic, i would like to express my honor and thanks to everyone who have donated to the IOTA development fund. In a space where most actions…
