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.
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…
Electric filters have many applications and are extensively used in many signal processing circuits. It is used for choosing or eliminating signals of selected frequency in a complete spectrum of a given input. So the filter is used for allowing signals of chosen frequency pass through it or eliminate signals of chosen frequency passing through it.

Every hobbyist wanting to dabble in radio has to – at some point – wind a coil or two, be it the antenna coil of an AM radio, a coil on a toroidal core for a bandpass filter in a communications transceiver or a centrally tapped coil for use in a hartley oscillator. Winding coils is not hard but quite time-consuming. There are different methods of making coils, depending on…
There is a long debate that Supercapacitors will overrule the battery market in the future. A few years back when Supercapacitors were made available, there was a huge hype about it and many expected it to replace the batteries in commercial electronic products and even in Electric Vehicles. But, nothing like that actually happened, because both Supercapacitors and…
Internet connectivity has become necessary nowadays as almost every electronic device needs an active internet connection to work properly. Although most of the devices have Wi-Fi connectivity options, but many devices and network routers still used Ethernet ports and cables to connect with the wired internet line. We previously learned about how data can be transferred over…
In electronics, surges are a very critical thing and it is a nightmare for every circuit designer. These surges are commonly referred to as impulse which can be defined as a high voltage, typically in a few kV which exists for a short duration of time. The characteristics of an impulse voltage can be noticed with a High or Low fall time followed by a very high rise time of…
Filters are commonly used in power and audio electronics to reject unwanted frequencies. There are many different types of filters used in electronic circuit designs based on the application but the underlying concept of all of them is the same, that is to remove unwanted signals. All these filters can be categorized into two types- Active filters and passive filters. The…
We all know that life is sustained on earth because of the sun as it provides sufficient heat energy to keep the earth warm. This energy is delivered by the sun in the form of Electromagnetic radiation which is usually called solar radiation. Some of the radiation is beneficial to humans while another radiation is harmful to all life.

We all know about an inverter - it is a device which converts DC into AC. And we previously learned about Different types of inverters and built a single-phase 12V to 220V inverter. A 3 Phase Inverter converts the DC voltage into a 3 Phase AC supply. Here in this tutorial, we will learn about the Three-Phase Inverter and its working, but before going any further, let…
The durability and dependability of an electronic circuit are highly dependent on how well it is designed considering all odds, which could practically occur when the product is actually in use. This is particularly true for all power supply units like AC-DC Converters, or SMPS Circuits because they are connected directly to the AC mains and a varying load which makes them…
When you want to design bipolar transistor circuits you need to know how to bias them. Biasing is applying electricity to a transistor in a specific way to make the transistor perform the way you want it to. There are mainly five classes of Amplifier - Class A, Class B, Class AB, Class C and Class D. In this article we will focus on biasing the transistor in a common emitter…
