This section covers basic electronics tutorials in various electronics domains. If you are an absolute beginner, this section is the starting point to learn the basic electronics concepts. Once you are the done with understanding the basic concepts, head towards the electronics circuits section and try your hands on few circuits.
If you are an RF Design Engineer or anyone who has worked with Wireless Radios, the term “Impedance Matching” should have struck you more than once. The term is crucial because it directly affects the transmission power and thus the range of our Radio modules. This article aims to help you understand what Impedance Matching is from the basics and will also help you to design…
For one of our projects, we tried to Interface LM35 Temperature Sensor with Arduino but were unable to do so. Yes, what seemed like an easy task became a whole day's effort. We initially assumed the sensor was defective, but after testing about 15 sensors, we saw the same issue over and over again; all of these sensors came from the same lot of 85 sensors we had in…
Anyone who deals with electronics will have come across waveform generator circuits like rectangular waveform generator, square wave generator, pulse wave generator, etc. Similarly, Bootstrap Sweep Circuit is a sawtooth waveform generator. Generally, the Bootstrap Sweep circuit is also called as Bootstrap Time Based generator or Bootstrap Sweep Generator.

Direct Online Starter or DOL is a simple electromechanical system designed for switching and protection of Induction motors.
We all know that motors consume electric power horribly and this high power consumption is the result of current drawn by the winding of the motor. So higher the current drawn by the motor, the higher will be the power…
We know that voltage, current, and power are measured in volts, amps and, watts and voltmeter, ammeter, and wattmeter are used to measure these parameters. Though these measuring instruments are manufactured with the care they may still give error readings at the customer end. So these instruments are calibrated to minimize the error. Here in this article, we will explain…
A True-RMS or TRMS is a type of converter which converts RMS value to equivalent DC value. Here in this tutorial, we will learn about true RMS to DC converter, how it works and how measurement methods can affect displayed results.
What is RMS?RMS is the abbreviation of Root Mean Square. By definition, for alternating electric current, the RMS value…
An operational amplifier is an integral part of Electronics, and we previously learned about Op-amps in various op-amp-based circuits and also built many oscillator circuits using op-amps and other electronics components.
An oscillator generally refers to the circuit which produces periodic and repetitive output, like a sine wave or square wave…
The induction motor is an A.C electrical machine that converts electrical energy into mechanical energy. Induction motor is used extensively in variously applications from basic domestic appliances to heavy industries. The machine has so many applications that are hard to count and you can imagine the scale by knowing that almost 30% of electrical power generated globally…
Every electronic system or device needs electric power to operate, whether it is from your walled AC supply or a battery. This electric power cannot be stored infinitely in any rechargeable device like batteries, condensers or Supercapacitors. So any portable devices like laptops or mobile phones are needed to be connected to AC power lines to recharge their batteries…
In some of our previous articles we have discussed about the basics of the transformer and its different types. One of the important and commonly used Transformer is Power transformer. It is very widely used for stepping up and stepping down the voltage at the electrical power generating station and distribution station (or substation) respectively.

Arduino was first introduced in 2005 aiming to provide a low-cost and easy way for novices and professionals to create devices that interact with their environment using sensors and actuators.
Before Arduino was introduced, the embedded design was viewed as a complex subject and hobbyists (or engineers) had to find a professional to get a working…
As mentioned in the last article where we discussed Electromagnetic Interference (EMI), almost all electronic products designed for commercial use and legal sales, are required to possess one or more certifications as a proof that the product complies with certain regulations/guidelines and has passed related tests. There are tonnes of regulations and they differ from place…
