Ubuntu Blog: Common use cases for digital twins in automotive
Digital twins have become somewhat of a buzzword in the past couple of years. But what exactly are they? A digital twin, as its name indicates, is a non-physical copy of a physical object. Just like a digital scan of a physical picture. This virtual element enables a real-time view of all relevant data coming from said object. Depending on the system being studied, specific sensors can be tracked and monitored. This allows for the replication of the system’s environment (adherence of the road, weather, surrounding objects or systems, etc). In this blog post, we will discuss digital twins and their use cases in automotive.

Improve your astrophotography quality with this automatic lens heater | Arduino Blog
Nighttime photography, and especially astrophotography, requires very long exposure. To get a good picture of the stars, you might leave the shutter open for several minutes. That gives nature plenty of time to produce dew on your lens, which can ruin the photo. The solution is a lens heater, but running that heater all night can consume a lot of power. That’s why Andrew Brocklesby built this automated lens heater that only activates when necessary.
Heated dew straps are common and affordable pieces of equipment for photographers. They slip over the frame of the lens and use electrical resistance to produce heat. Like the rear defroster on your car, that heat helps get rid of the condensation that forms as humid air comes into contact with a cool surface. Brocklesby’s device takes into account that the condensation doesn’t form unless both the ambient temperature and humidity are at specific levels. If they aren’t, then there is no need to activate the lens heater and waste power.

Improve your cooking with home automation | Arduino Blog
Cooking is something many of us love to do at home. There are few feelings more rewarding and satisfying than throwing together a delicious meal in your own kitchen and sharing it with family or friends.
However, cooking can be tough. There are lots of things to pay attention to, lots that can go wrong, and lots of preparation and planning to stay on top of. The good news is that home automation has many different solutions to make the cooking process easier, more fun, and more organized.

The Inner Machinations Of The Arduino Are An Enigma
Arduinos have been the microcontroller platform of choice for nearly two decades now, essentially abstracting away a lot of the setup and lower-level functions of small microcontrollers in favor of sensible IDEs and ease-of-use. This has opened up affordable microcontrollers to people who might not be willing to spend hours or days buried in datasheets, but it has also obscured some of those useful lower-level functions. But if you want to dig into them, they’re still working underneath everything as [Jim] shows us in this last of a series of posts about interrupts.
