The full form of LED is Light Emitting Diode. LEDs are special type of semiconductor diodes which emit light in response to a potential difference applied across their terminals, hence the name light emitting diode. Just like a normal diode LEDs also have two terminals with polarity, namely anode and cathode. To illuminate an LED […]

Simple Electronic Dog Whistle Circuit Explained
An electronic dog whistle is a device that generates ultrasonic sound waves and is used for training dogs and for controlling excessive barking habit. Because dogs and domestic cats can hear ultrasonic frequencies, humans cannot, this dog whistle device is employed to train these animals. It is also sometimes known as a silent whistle or […]
What are the Different Types of Transformers? Explained
In this post I am going to explain different types of electrical transformers that are used in a wide variety of applications. Transformers can be classified in many different ways, for example: based on their input / output character, voltage, frequency, application, power handling capacity etc. In this post we will be exploring all the […]
Different Types of UPS systems – Explained
In this post I am going to explain different types of uninterruptible power supply (UPS) that are available in the market and how they are classified according to the consumer’s requirement. We will also explore the different types of UPS’s block diagram to understand their technical difference between them. UPS systems are a type of […]
Clipper and Clamper Circuits Explained
In this post I am going to explain clipper and clamper circuits. The clipper and clamper are called wave shaping circuits because they convert the incoming signal wave to another kind of useful wave. They are used widely in power supplies, filter circuits, RF transmitters / receivers, voltage suppressors, audio amplifiers and the list goes […]
Communication Protocols in Microcontrollers Explained
In this post I am going to explain various communication protocols that are used by microcontrollers, microprocessors and ICs for communicating with various sensors, electronic drivers, input and output devices. We will see: Why do communication protocols exist in electronics? UART protocol. I2C or IIC or “I squared C” protocol. SPI or Serial Peripheral Interface […]
