To learn about RGB led and the difference between single-color LEDs, it is important to make a circuit using a microcontroller such as ESP32 or Arduino and RGB led. Then it is important to manage that circuit using a program. There are some simulators available to make the beginner of IOT learn such concepts without even having the IOT devices available. However, to get real results, using the circuit components and making the actual circuit is important. In this article, using two different examples, the way to use the RGB led is given. In example 1, the actual circuit using ... Read More

To start learning IoT, first, it is important to learn how to make circuits using a breadboard and a microcontroller. Then it is important to control that circuit using a program. There are some simulators available to make the beginner of IOT learn both these concepts without even having the IOT devices available. However, to get real results, using the circuit components and making the actual circuit is important. In this article, using two different examples, the way to start IOT programming is given. In example 1, the Wokwi simulator is used and in example 2, the actual circuit using ... Read More

In this article, using two different examples, the use of potentiometers is demonstrated using ESP32. In the first example, the trimmer type of potentiometer is used to vary the voltage between 0 and 3V. In the second example, the slider potentiometer is used on Wokwi Simulator to show the control of a servo motor. Wokwi simulator is software that can be used for running the code and virtually testing the results without buying the components. The actual diagram of the components is often different from those used in Wokwi, so the actual form of the slider potentiometer is given in ... Read More

A simple buzzer can be connected to the ESP32 controller for producing sound. It can also be used to produce melodies. In this article, using two different examples, the C code is used on Arduino to make the buzzer play the melody. In the first example, “Twinkle Twinkle Little Star”, the poem’s notes are played and in the second example, another famous poem “Jingle Bell” is used for playing the note while making two colored LEDs on and off to create a light show with music. Example 1: Playing the poem notes using buzzer and ESP32 The circuit is made ... Read More

The technological revolution has caused computers to literally evolve. It would appear that computers have taken over every aspect of our lives. There have been other non-economic factors in the past that have contributed to the computer's rise to prominence. While the primary function of early computers was calculation, this is now the least essential function of modern computers. Electronic digital computers were first developed for the sole purpose of solving equations. In order to get more done in less time, humans drove the development of computers. As the IT industry is concerned about the rise of mobile devices like ... Read More

Introduction A dependable internet connection is crucial in today's digital environment for both business and entertainment.

Enter the Internet Service Provider (ISP) hierarchy – a fascinating network of players working behind the scenes to keep us connected. What is an Internet Service Provider (ISP)? What exactly is an Internet Service Provider? ISPs are businesses that give internet access to users in exchange for a fee, allowing them to connect to the internet and utilize various online services. Definition and function of an ISP An ISP ... Read More

AHB (Advanced High-performance Bus) and APB (Advanced Peripheral Bus) are two bus protocols that are extensively used in the design of complex digital systems. The key difference between AHB and APB is their speed and intended usage. AHB is designed for high-performance applications requiring fast data transmission rates and low-latency communication, whereas APB is designed for slower peripherals not requiring high-speed data transport. Read this article to find out more about AHB and APB and how they are different from each other. What is AHB? AHB is an ARM-designed high-performance bus protocol for connecting high- speed peripherals and memory in ... Read More

There are two different technologies namely, CVT (Constant Voltage Transformer) and UPS (Uninterrupted Power Supply) that are used for providing power conditioning and protection. A CVT is an electrical device used to provide a constant output voltage despite variations in the input voltage or load, whereas a UPS is an electronic device used to provide power during power outages and voltage fluctuations. Read this article to learn more about CVT and UPS and how they are different from each other. What is a CVT? A CVT is an electrical device that is used to provide a constant and stable ... Read More

mAh (milliampere-hours) refers to a battery's capacity, or the amount of energy it can store and deliver. NiMH (nickel-metal hydride) refers to the chemical composition of the battery. Read this article to find out more about NiMH and mAH batteries and how they are different from each other. What are NiMH Batteries? In NiMH batteries, hydrogen is used to store energy. Nickel Metal Hydride consists of a nickel hydroxide positive electrode plate, a hydrogen ion negative electrode plate, potassium hydroxide or another alkaline electrolyte, and a separator. NiMH batteries are commonly used in cell phones, digital cameras, pagers, electric toothbrushes, ... Read More

An oven uses gas or electricity to heat the food. Induction cooktops, on the other hand, use magnetic energy to warm the cookware and the food that is inside. The primary distinction between the oven and induction cooktop is the process they use to heat the food. The induction cooktop is quicker and more energy efficient compared to other cooking techniques that are used to cook food. The oven is slower at cooking compared to an induction cooktop, but it allows different cooking methods such as roasting, baking, and broiling. Read this article to find out more about Induction Cooktop ... Read More
