Again, we are talking about the regular rocker/piano switches which are commonly used everywhere. Previously we published an important article - How to Interface a Piano/Rocker Switch (SPST) With ESP32 Arduino. These days, concealed conduit wiring with modular components are standard. There has been standardisation across the globe for compatibility. I have written before that these came into … [Read more...]

Detailed article on computer hardware parts like RAM, Motherboard, Processor, Graphics card. Hardware also covers topics on hardware of Server, Single Board Computers like Raspberry Pi to Libre Hardware Projects.
Types of Flip-Flop in the Context of Arduino
Usually, by the word "flip-flop", we understand one on and another off. That is the usual reason behind searching our guide on Arduino Flip-Flop Blinking LED With Push Button. While that is true (to some extent) as a visual effect, for the advanced flip-flop, we need to know some theory. When we are programming 2-3 LEDs, the logic remains easy, hence we could avoid the theoretical … [Read more...]
What is a Smart Grid and What Are the Challenges with Smart Grids
The term smart grid refers to the strategy of focusing on IT technical and regulatory innovations in grid control (grid intelligence) with which the utilization of the existing infrastructure can be improved. This is intended to keep the time- and capital-intensive expansion of the physical infrastructure (overhead lines, underground lines, transformers) as low as possible or to avoid … [Read more...]
What to Know About FPGA in Electronic Design Service
Before the development of CAD, electronic circuits were designed and manufactured by hand. Some advanced stores used geometric software to create the tracks with the Gerber photoplotter. The process was essentially graphic, with a transition from the electronic diagram to a layer for the UV insolation machine. The development of FPGA circuits is often referred to as programming. In this context, … [Read more...]
What is Active Noise Reduction (ANR)
Anti-noise is also known as Active Noise Reduction is colloquially understood as a sound that is artificially generated to extinguish sound using destructive interference. For this purpose, a counter-signal is generated that corresponds to that of the disturbing sound but has the opposite polarity. Two different problems have to be distinguished: If a noise source emits sound, one tries to … [Read more...]
How to Replace delay() with millis() : Arduino Programming
In many of the sketches shared by us have the millis() instead of delay(). Not always it is possible to explain a function within a guide on how to do a thing. In this article, we will explain about millis() and provide some easy examples so that you can reproduce yourself. It is normal that the Arduino users initially use the delay() function. The main reason is the blink example is the thing … [Read more...]
Arduino LED Candle : Some Codes to Help You
Thanks to China for making various designs of LED candles available all over the world. Indeed, most of these LED candles are not closest to the real candle, but they do give us the idea to think around playing around creating our microcontroller controlled LED candle. I was looking for a realistic feel and soon discovered that two people in project sites already worked a lot behind the creation … [Read more...]
How an Engine Generator Set Works
A generator set is an autonomous device capable of producing electricity. A generator set is a machine that moves an electric generator through an internal combustion engine. They are commonly used when there is a deficit in the generation of electricity from somewhere, or when power cuts are frequent. Likewise, the legislation of the different countries may require the installation of a generator … [Read more...]
What is On-Board Diagnostics (OBD)?
On-board diagnostics (OBD) is a vehicle diagnostic system. During driving, all exhaust-influencing systems are monitored, in addition to other important control units whose data is accessible through their software. Any errors that occur are displayed to the driver via an indicator light and permanently stored in the respective control unit. Error messages can then be queried later via … [Read more...]
What is a Smart Speaker?
A smart speaker is an Internet-connected speaker that transmits music or voice wirelessly and integrates the functions of an intelligent personal assistant (IPA) via non-invasive voice control and speech recognition. No uniform term has yet developed for these devices, which is why terms such as intelligent loudspeakers and networked loudspeakers are also used to denote them. The speaker … [Read more...]
Best Earbuds for Samsung Smartwatches
LTE smartwatches are great since we can avoid carrying our fragile, costly smartphones everywhere. One of the two uses of smartphones is handling calls and listening to music. While some apps allow the smartwatches to use the cameras of the smartphones, smartwatches are largely a device without their camera. A basic question many users tend to ask (I was among them once), why we will buy … [Read more...]
