The electric name of Silicon controlled or the semiconductor controlled rectifier (SCR) is Thyristor. These are the four-layered semiconductor devices where three terminals are known as the anode, the cathode, and the gate. Based on the triggering applied at the gate the device can be treated as a switch or used as a rectifier. These SCRs are unfit for amplifications. SCRs are responsible for conducting the flow of current in a single direction. Hence it is also a unidirectional device. It … [Read more...]
Ohmmeter Circuit Diagram and Working Principle
While testing, repairing or troubleshooting electronic equipment, you use different meters and different types of test equipment to test proper circuit currents, resistances, voltages and to decide whether the wiring is faulty. Without knowing the operation of the Ohmmeter, it is not possible to connect this instrument to a circuit to test the component. However, to be a competent technician, we need to be competent to do more than merely read a test instrument. For that we need a basic … [Read more...]
Different Types of Arduino Boards and Its Uses
Arduino board was designed in the Ivrea Interaction Design Institute intended for students without a background in electronics and programming concepts. These Arduino boards started altering to adapt to new requirements and challenges, separating its present from simple 8-bit boards to products for IoT (Internet of Things) applications, 3D printing, wearable, and embedded applications. All boards are entirely open-source, allowing users to build them separately and finally adapt them to their … [Read more...]

IC 741 Op-Amp Tutorial and Characteristics
The acronym of the term Op-Amp is an operational amplifier and it is a one type solid state integrated circuit. In the year 1963 the first op-amp is manufactured by “Fairchild Semiconductors”. The op-amp is the basic building blocks of analog electronic circuits that perform a various types of analog signal processing tasks. Operational amplifiers use external feedback to control its functions and these are the multipurpose devices in all electronic devices. Op-Amp has two inputs and one output … [Read more...]
8051 Microcontroller Architecture and Block Diagram with Applications
The 8051 Microcontroller is one of the basic types of microcontrollers, designed by Intel in 1980s. This microcontroller was based on Harvard Architecture and developed primarily for use in embedded systems technology. Normally, this microcontroller was developed using NMOS technology, which requires more power to operate. Therefore, Intel redesigned Microcontroller 8051 using CMOS technology and their updated versions came with a letter C in their name, for instance an 80C51 it is an 8 bit … [Read more...]
Know about Different Types of Sensors with their Applications
In our day-to-day life we frequently use different types of sensors in several applications such as IR sensor used for operating television remote, Passive Infrared sensor used for automatic door opening system of shopping malls and LDR sensor used for outdoor lighting or street lighting system, and so on. In this article we will discuss about a few types of sensors and their applications in brief. But, primarily we must know what is a sensor. … [Read more...]
LM324 Comparator Circuits Working and Applications
The LM324 operational amplifier IC can be worked as a comparator. This IC has 4 independent operational amplifiers on a single chip. This a Low Power Quad Operational Amplifier and it has high stability, bandwidth which was designed to operate from a single power supply over a wide range of voltages. The quad amplifier can operate at supply voltages as low as 3.0 V or as high as 3.2 V with quiescent currents about one fifth of those associated with the MC174. … [Read more...]
Know all about Raspberry Pi Board Technology
The Raspberry pi is a single computer board with credit card size, that can be used for many tasks that your computer does, like games, word processing, spreadsheets and also to play HD video. It was established by the Raspberry pi foundation from the UK. It has been ready for public consumption since 2012 with the idea of making a low-cost educational microcomputer for students and children. The main purpose of designing the raspberry pi board is, to encourage learning, experimentation and … [Read more...]
