Multi-cloud is the use of multiple cloud computing and storage services from different vendors in a single heterogeneous architecture by an organization to improve the capacity and cost of cloud infrastructure. This also refers to the distribution of cloud assets, software, applications, etc., across multiple cloud hosting environments. With a typical multi-cloud architecture that uses two or more … [Read more...]

Here also you will get unique articles and news on computer hardware, Software, Networking and Protocols.
Data Protection on the Internet
Data protection on the Internet refers to the application of data protection to data transmitted over the Internet. It involves applying control over the type and amount of information that is shared about an individual on the Internet and who has access to that information. Internet Privacy is a subcategory of computer privacy. As a rule, people have a right to self-determined anonymity on the … [Read more...]
Basics of BJT Transistor
In our previously published articles, we have discussed about MOSFET and Darlington Transistor. These three articles including this one are important for Arduino users with a lesser idea about these semi-conductors. Our target is to distribute the basic knowledge so that they decide and purchase the correct type of transistor. The discovery of the BJT transistor made it possible to effectively … [Read more...]
What is Confidential Computing?
Confidential computing is a privacy enhancing computing methodology intended to protecting data. The method isolates sensitive data during processing into a protected CPU enclave and only authorized programmers who have access to the contents of the enclave—the data that is being processed. The methods used to process it—and they are invisible and unknowable to anyone else, including the cloud … [Read more...]
How a MOSFET Works
In our previous article on Darlington Transistor, we have explained the classification of transistors. The operating principle of MOSFETs is about 20 years older than that of the BJT transistor. An isolated gate field-effect transistor more commonly known as MOSFET (which stands for metal-oxide-semiconductor field-effect transistor). It is a type of field-effect transistor (FET). Like all … [Read more...]
What is a Darlington Transistor (Such as TIP120)?
Often it is observed that TIP120 is used in some circuits created with Arduino UNO or ESP32. It is a Darlington pair (it is a transistor). In many circuits, we can either use a transistor or a MOSFET. For example, in our previous guide, 5050 LED Strip with Arduino, we have mentioned that we can use either transistors or MOSFET. The sentences are not fully correct - a MOSFET is also a transistor. … [Read more...]
5050 LED Strip with Arduino/ESP32
5050 LED Strips are cheap LED strips which resemble costlier Neopixel strips but the LEDs in 5050 LED Strips are not individually addressable. That means you can use the animations as one coloured LED at one time. You can run the common old animations such as change of colour, dimming effect etc. But we can not run tricky animations such as chase. 5050 LED Strips are a good choice for interior … [Read more...]
NeoPixel Ring (24 Bit) Spindicator/Chase with Arduino
Spindicator means spinning indicator, Apple calls it "spinners". It is a very common animation used to show the loading process progress in many software including Windows 10 and 11. This project only contains the code which will create the animation (which is essentially the chase effect). In this basic guide, we have not shown PWM to control the progress of the indicator. This guide is the … [Read more...]
What is User Experience (UX) Design
User experience design describes the process of designing a purchase pre-decision phase of a user in a service or product interaction, for example with the help of digital graphical user interfaces, and forms part of the phenomenon of user experience. This interaction with a product is created through the interplay of usability, usability, visual design, interaction design, content strategy, user … [Read more...]
Robot Ethics : The Main Fields of Questioning
Robot ethics is the application of ethics to robotics. It deals with the development, manufacture and use of robots. With the increase of robots in human life and the realization that robots are not just pure tools, but agents, companions and avatars, the question arises about an assessment of the ethical challenges facing humans. In 2004, the first international symposium on robot ethics was held … [Read more...]
Arduino: Display Potentiometer Readings on 7 Segment LED Display
There are various practical needs to output the value of a potentiometer on a digit 7-segment display without making it super complicated. Things such as an audio player require a display of the audio control knob by using some sort of logic with this kind of project. In our earlier articles, we have discussed about PWM and control of a line of LED with potentiometer. Both of those articles are … [Read more...]
