Electronic circuits and devices are getting smaller and exponentially more complex. When they were large, they can be tested them with test probes on the bottom of the board. There were issues with such method but still it was a way. Today, components are mounted on both sides of a circuit board, hence no place of attachment are left for the test equipment. Joint Test Action Group (JTAG) is a … [Read more...]
What to Know Before Buying a Digital Audio Player (for Audiophiles)
Digital Audio Players can play digital audio files. Sales of the Portable Music Players (PMP) have declined with the increased penetration of the flagship smartphones. Mid-range to high-end Digital Audio Players are designed for sound engineers, musicians and audiophiles. There are a lot of things to learn about them before you purchase one since the price tag going to be $1000 to … [Read more...]
What is Floating-Point Unit (FPU)
A floating-point unit (FPU) is a part of a processor, specifically designed to perform operations on floating-point numbers. All processors incorporate at least addition, subtraction, and multiplication. The fused multiply–add operation is increasingly being implemented. It is very useful for speeding up certain algorithms. Most processors also incorporate division and square root, but these … [Read more...]
How Analog-to-Digital Converter (ADC) Works
An analogue-to-digital converter (ADC) is an electronic device whose function is to translate an analogue quantity into a digital value encoded on several bits. The converted signal is usually an electrical voltage. As we have explained before, the GPIO pins of any microcontroller board such as Arduino, ESP32 etc can handle digital input or output only. The analogue pins of Arduino are an … [Read more...]
How to Save Sensor Data from ESP32/Arduino to InfluxDB
There are some databases which are suitable for use with Arduino, ESP32 etc microcontrollers. We can indeed use MySQL (and PHP) to create IoT projects like this one. However that approach requires own API server and such method has limitations. It is a complicated method and presents app and web development moving away from PHP and MySQL/MariaDB. These days it is convenient to use Create React App … [Read more...]
What is Multitasking?
The term multitasking refers to the ability of an operating system to perform multiple tasks concurrently. In general, the processor also offers supporting hardware structures for this. The various processes are activated alternately at such short intervals that the impression of simultaneity is created. Multitasking is thus a variant of a time-multiplexing process. If a computer has several CPU … [Read more...]

How an Air Purifier Works
An air purifier is a device designed to reduce domestic and industrial pollution. It filters the air, removes certain pollutants, as well as bad odors. Air purifiers are used by industry to filter and remove toxic residues, in hospitals and airlines to prevent the spread of viruses and bacteria. They are also used in offices and homes to improve hygiene, the quality of life of each individual and … [Read more...]
How a Dishwasher Works
The dishwasher washes everything in it using pressurized water jets, and provided that these jets are not blocked and the nozzles are well uncorked. One, two or three rotating arms equipped with sprinklers sprinkle warm to very hot water on the dishes, according to a cycle whose duration is calculated to ensure removal of food crusts whatever their nature (burnt fats, caramelized sugars, various … [Read more...]
What is COB LED? How LED Chip On Board Works
Chip-on-board technology (COB) is a method for the direct assembly of unpackaged semiconductor chips on printed circuit boards to an electronic assembly. The term COB is used for all assemblies that contain the naked semiconductor, whereas originally it was understood exclusively as assemblies with chip-and-wire technology. By eliminating individual packaging of semiconductors, the final product … [Read more...]
