A microcontroller is essentially a small computer on a chip, like any computer, it has memory and usually programmed in embedded systems to receive inputs, perform calculations and generate output. Unlike a processor, it incorporates the memory, the CPU, I/O and other peripherals on a single chip like shown in the layout below.

Op-Amp, short for operational amplifier is the backbone of Analog electronics. An operational amplifier is a DC-coupled electronic component which amplifies Voltage from a differential input using resistor feedback. Op-Amps are popular for its versatility as they can be configured in many ways and can be used in different aspects. An op-amp circuit consists of…
Power electronic switches like BJT, SCR, IGBT, MOSFET, and TRIAC are very important components when it comes to switching circuits like DC-DC converters, Motor Speed Controllers, Motor Drivers, and Frequency Controllers etc. Each device has its own unique property and thus they have their own specific applications. In this tutorial we will learn about the TRIAC, which is a…
Wireless Charging is the process of recharging battery powered electronic devices without directly tethering them using wires and cables to a power source. The process gives users the freedom of charging their phone on the go without the need to plug to power outlet. This means wireless charging enabled smartphones and other devices could be charged by simply placing them on…
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…
