Introduction to Arduino | Pin Function of Arduino | Working Process of Arduino Introduction to Arduino | Pin Function of Arduino | Working Process of Arduino Introduction To Arduino Arduino is an Italian company that designs and manufactures Open Source Hardware (Microcontroller) and Open Source software or IDE (Integrated Development Environment). Arduino hardware is such a programmable computerized platform, by working on which the user can combine the hardware and software and prepare the electronic brain according to his own and can control the electronic devices from that electronic brain. What is arduino? If you want to understand more easily, then we can say that Arduino microcontroller is an empty brain, in which you can upload memory by coding or programming through arduino software, so these are called open source. Arduino works like a CPU of a board computer. Right now the microcontroller of the arduino of this time that we can take up is lik...

What is Microprocessor? | Block Diagram of Microprocessor | Application of Microprocessor What is Microprocessor? | Block Diagram of Microprocessor | Application of Microprocessor Basic Detail Of Microprocessor The  microprocessor is a semiconductor device consisting of electronic logic circuits manufactured by using either a large scale(LSI) or very large scale integration(VLSI) technique. The microprocessor is capable of performing computing functions and making decisions to change the sequence of program execution. In large computers, the central processing unit(CPU) performs these computing functions and it is implemented on one or more circuit boards. The microprocessor is in many ways similar to the CPU, however, the microprocessor includes all the logic circuitry(including the control unit)on one chip. The microprocessor consists of the following three segments which is shown in below diagram. Block Diagram of Microp...

What is Computer? | Characteristics of Computer | Limitations of computer | Types of Computer  Definition A computer is a machine that processes data according to set of instructions stored within the machine. What is Computer? |  Characteristics of Computer | Limitations of computer | Types of Computer  It receives data as input, processes the data, such that performs arithmetic and logical operations on the same and produces output in the desired form on output device as per the instructions coded in the program. The processing function of the computer is directed by the stored program, a set of codes instructions stored in the memory unit, which guides the sequence of steps to be followed during processing. Characteristics Of Computer The following are the characteristics which make a computer an indispensable unit: ✓ Speed ✓ Consistency ✓ Accuracy ✓ Flexibility ✓ Reliability ✓ Large storage capacity ...

Advantages and Disadvantages of Electromagnetic Relay There are many Advantages, Disadvantages and Application of Electromagnetic Relay which will be mentioned in this article Advantages and Disadvantages of Electromagnetic Relay Advantages Of Electromagnetic Relay ✓ Electromagnetic relays have fast operation and fast reset. ✓ They can be used for both a.c.and d.c.systems for protection of a.c.and d.c. equipments. ✓ Electromagnetic relays operating speeds which has the ability to operate in milliseconds are also can be possible. ✓ They have the properties such as simple, robust, compact and most reliable. ✓ These relays are almost instantaneous. Though instantaneous the operating time of the relay varies with the current. With extra arrangements like dashpot, copper rings etc. ✓ slow operating times and reset can be possible. Disadvantages Of Electromagnetic Relay ✓ High burden level instrument transformers are re...

How Potentiometer Works ? | Various Types of Potentiometer Definition : Potentiometer is the instrument which is use for measurement of potential difference, current and resistance accurately. How Potentiometer Works ? | Various Types of Potentiometer There are mainly two types of potentiometer  1. D.C. Potentiometer 2. A.C. Potentiometer These two types are described in detail below (1) D.C.Potentiometers D.C. potentiometer further classified in two types: 1. Simple Potentiometer 2. Crompton Potentiometer Now Description of these two potentiometer are as following below: Simple Potentiometer For the accurate measurement of potential difference, current and resistance the potentiometer is one of the most useful instruments. The circuit diagram of simple Potentiometer is shown in below figure: Circuit Diagram of simple Potentiometer Its principle of action is that an unknown e.m.f. or  po...

How Galvanometer works?? What is Galvanometer? A galvanometer is a device which is used for detecting and indicating an electric current. It is a one type of electromechanical device. It is used for to indicate the direction of current flow in conductor. A galvanometer is type of Ammeter. Working Principle Torque acts on a current carrying coil drape in the uniform magnetic field so coil make be rotates. So detection of moving coil galvenogalva is directly proportional to the current flowing in the coil. Construction The construction of the moving iron galvanometer is shown in below image. Working Let take a coil PQRS which has L length and width 'b'. It's arrange in a such a way that the plane of coil stay parallel to the magnetic field. Here current through the coil is I. Here coil sides PQ and RS perpendicular to the magnetic field so it's experience the force by each side. F = B I L   These ...

Ammeter is device which use for measurement of electric current. Symbol of Ammeter Ammeter is always connected in series to measure a current. Circuit Diagram Working Ammeter must be connected in series, because current is same in series connection. So, When current passed through ammeter, it will show how amount of current passed through in conductor or wire in ampere. It has very law impedance, so loss of power becomes low, If we connect ammeter in parallel than power loss make be high and device may damaged. Types of ammeter According to measurements of current  in different types of supply DC Ammeter AC Ammeter There are generally two types of ammeter Analog Ammeter Digital Ammeter  Digital ammeter shows accurate measurement as compared to analog ammeter

High Temperature Alarm Device We use high temperature alarm device for security purposes, because security is necessary everywhere. High Temperature Alarm Device Make alarm device by easy steps at home, video of this device is shown below check now👇👇👇👇 We use high temperature alarm device for security purposes, because security is necessary everywhere. Some places where we use this device, Bank 🏦  Hospital    Industry  School College   Gas station Petrol pump  Etc..   How it works? Due to some fault or incident, Fire 🔥 will be produced. This device most of place on the upper side, Temperature sensor is used in this device. So, when fire is come touch with this device, then alarm start horning. Temperature ranges is fixed previously on it, so if fire cross the range of temperature which set previously then this device come in working condition. So, we can taking action agai...

How Voltmeter Works? How Voltmeter works? Voltmeter is a basic meter to use for measure a electric potential difference in volts. There are generally two types of voltmeter                     1. Analog voltmeter                    2. Digital Voltmeter In analog voltmeter, pointer is used across calibrated scale. Pointer is move around the scale according to potential difference. Analog voltmeter is not shows perfect calibration as compare to digital voltmeter. In digital voltmeter, analog to digital converter is used, so first it's convert analog to digital and digits are shown on display. Digital voltmeter is shows the perfect calibration as compare to analog voltmeter. When voltage to be measure, voltmeter must be connected in parallel. Voltmeter has high value of resistance, so if we connected it in series, then resistance ...
