I was eager to write another article because it had been a long time since we had seen each other (or e-met). SnapStack Solutions\’ Jordan has arrived.
Embedded systems are more common than we think, but what are they and how do we utilize them?
An embedded system, unlike a laptop, is intended for and devoted to one single item or equipment, and is used to govern its functioning. The ‘device or machine\’ might be anything from a wristwatch to a major medical imaging system or robot, and the embedded system is usually housed within it, as the name indicates.
Because of its control role, the embedded system must be able to monitor sensor inputs such as temperature, voltage, or video, conduct control and perhaps analytical computations on the observed data, and send appropriate outputs to actuators such as displays, lights, motors, or valves. As a result, the embedded system must have input ports that are electrically and physically compatible with the sensors it is monitoring.
The number of inputs and outputs they must regulate, as well as the speed and complexity of the control tasks required, determine the scale of embedded systems. For example, a smartwatch controller would need to be built on a single, tiny printed circuit board. An industrial PC, on the other hand, is a more common option for bigger applications because of its flexibility and scalability, as well as, to some extent, its use of standardized hardware and software components.
When compared to desktop or laptop computers, embedded systems have both benefits and drawbacks, however, the status of particular characteristics as an advantage or disadvantage varies depending on the application.
They might be less expensive since they are specialized in a specific application. For example, high-performance graphics may be omitted, and some systems may not even have a graphical user interface. If the intended application does not require high-performance computing, other systems may have CPUs with lower performance and power consumption. Low-power devices would also be possible, with some even running on batteries. Embedded systems can also be quite small and easy to identify, particularly if they don\’t require a big free space environment for ventilation.
Embedded systems are also very dependable since they must be in order to satisfy the needs of their applications. They can withstand extreme climatic and electrical conditions, as well as possible intentional damage – which is helpful in public places.
Reassigning embedded systems to a different application might be challenging since they are often built to tackle a single task. There may be a limited number of spare communication ports or expansion card slots or none at all. Furthermore, unlike desktop Windows, its RTOS will not support a large selection of software programs — and even if it did, the power and memory available to run them may be restricted.
When comparing equivalent performance desktop and embedded computers, the embedded system will almost always be more costly. This is because embedded system manufacturing quantities will be lower, resulting in fewer possibilities for cost amortization. For increased longevity and dependability, embedded system designs tend to employ higher quality and more costly materials and components.
I noted before that embedded systems may be found in a wide range of applications, starting with smartwatches. Other minor instances are GPS receivers, digital cameras, gaming consoles, wireless routers, photocopiers.
In this perspective, smartphones are intriguing devices. They have many of the features of an embedded system, but they can also accept and execute user-specified applications, making them similar to desktop PCs in that regard.
In the case of programmable logic controllers (PLCs), which are widely employed in industry, a similar argument might be made. They\’re usually built on an industrial PC architecture, so while they have embedded system features like robust construction and an RTOS, they also have a desktop PC-like capacity to accept other programs – at least when they\’re shipped from their original manufacturer. Other larger-scale — and more specialized – uses include: industrial robot arm controllers, traffic light controllers, security systems, aerospace applications, process control systems used in manufacturing.
A horticulture controller is a current example of an embedded system that is used to increase plant and agricultural yield through greenhouse automation. Sensors and actuators linked to a greenhouse environment climate control computer monitor and control temperature, humidity, electrical conductivity, pH, carbon dioxide (CO2), fogging, and shading, as well as read external weather conditions through a weather station.
The data obtained aids in the regulation of not just particular factors inside the internal growth environment, but also in the saving of time, energy, and labor. There\’s also an irrigation schedule for up to five different feed formulas and expandable zones in the program.
Home automation controllers are another increasingly common use for embedded systems. Security, access control, heating, and air conditioning, lighting, and entertainment may all be integrated and controlled through one system. These systems can also be linked to the Internet of Things (IoT) for remote monitoring and control.

Enjoy your weekend ahead!
Hello everyone, I hope the good weather gives you such positive vibes as it does to me. This is Jordan from SnapStack Solutions and this week I am joining you again to share another article with you. This week we are in an artsy mood, so I wanted to write about the creative part of the IT world. Using the advantages of good UI/UX design is more important than most people realize.

Difficult as it is to understand, the internet is prone to change as well. At its inception, the internet was a simple text-based medium but now, it is a dynamic platform that powers nearly every aspect of our lives. However, the current web infrastructure, often referred to as Web2, is characterized by centralization, data privacy concerns, and limited user control. Web3 is about to change all that.
