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.
Most of the consumer electronic devices around us, such as mobile phones, TVs, Radios, and MP3 players, are a combination of Digital and Analogue electronics. Wherever wireless transmission/reception, or audio signals are involved in an electronic design, we will need periodic oscillating electronic signals. These signals are called Oscillating signals and are very useful in…
In the previous tutorial of Half Subtractor Circuit, we had seen how computer use single bit binary numbers 0 and 1 for subtraction and create Diff and Borrow bit. Today we will learn about the construction of Full-Subtractor circuit.
Full Subtractor CircuitHalf-Subtractor circuit has a major drawback; we do not have the scope to provide…
The term Multiplexer which is also commonly called as “MUX” or “MPX” refers to selecting one output of the many available inputs. Professor Shankar Balachandran (IIT-M) explains multiplexing as the method of transmitting a large number of information units over a small number of channels or lines and a Digital Multiplexer is a combinational Logic circuit that selects binary…
In previous tutorials, we have seen how computer use binary numbers 0 and 1 and by using an adder circuit computer will add those digits to provide SUM and Carry Out. We have already covered Half Adder and Full Adder circuits in previous tutorials. Today we will learn about Subtractor circuits. Subtractor circuits use this binary numbers 0, 1 and calculate the subtraction.…
Decoder is type of combinational Circuit which decodes a small bit value into large bit value. It is normally used in combination with encoders which does exactly the opposite of what a decoder does, so read about Encoders here before you proceed with Decoders. Again just like Encoders there are many types of Decoders as well but the number of output lines in a decoder will…
Encoders, as the name suggest, encodes a larger bit of information into a smaller bit value. There are many types of encoders based on the number of inputs and outputs and based on how it operates. But every Encoder has one underlying rule, the number of output lines on an Encoder will always be less than number of input lines. We will learn more about encoders, what is…
Computers use binary numbers 0 and 1. An adder circuit uses these binary numbers and calculates the addition. A binary adder circuit can be made using EX-OR and AND gates. The summation output provides two elements: the first one is the SUM, and the second one is the Carry Out.
When we use the arithmetic summation process in our base 10 mathematics…
A capacitor is one of the most used electronic components. It has the ability to store energy inside it, in the form of an electrical charge producing a static voltage (potential difference) across its plates. Simply, a capacitor is similar to a small rechargeable battery. A capacitor is just a combination of two conductive or metal plates places parallel, and are…
The entire range of electronic components can be divided into two broad categories: active components and passive components. The Passive components include the Resistor (R), the Capacitor (C) and the Inductor (L). These are the three most used components in electronics circuits, and you will find them in almost every application circuit. These three components together in…
Power supplies can be classified into two broad categories: AC power supply and DC power supply. Since only AC power can be generated economically, most electrical machines run on AC power. However, the standard voltage and frequency from generating stations may not suit certain industrial machines. This is where power electronic converters like inverters and cycloconverters…
It is estimated that there will be around 20.4 billion devices connected to the internet by 2020, well how big is this number? To give a figure the total world population is 7.6 billion, meaning there will be around 3 devices connected to the internet for every human on the earth. This makes it evident that Internet of things will have a major role and strong impact in the…
We have built many Arduino Projects and all the time we have used official Arduino IDE to program the Arduino. But do you know that we can also program the Arduino using your Smart phone. Sometimes we don’t have any PC or laptop to program our Arduino boards. We can still program it using our Android mobile, Thanks to OTG (On the Go) adaptor.
You…
