Chapter 1: The Internet of Things in a Nutshell

1. Some technologies associated with IoT are smart homes, smart cars, and IIoT/Industry 4.0.
2. Voice user interfaces such as Alexa and Siri are used more and more to control internet-connected devices.
3. It does not make sense to make every device smart. The more features a device has, the more likely it is for problems to appear. Would you rather have a traditional vacuum cleaner that works 99% of the time, or a vacuum cleaner that only works when a wireless network connection is available but that shows its status in an app?
4. Prototypes are used to find out if your idea works or not. They can be developed in a quick and dirty way and are all about getting the desired result fast.
5. No! The beautiful thing about prototyping is that you don't need to be an expert in every area—especially in the Arduino community, where you will find code snippets and diagrams for most common sensors and actuators. Combining example snippets and adding a little bit of logic to the code might do the job for a first version.
