Introduction A beeper, buzzer, or other auditory signaling device can be mechanical, piezoelectric, or electromechanical in nature. This is mostly used to transform the audio signal into sound. It is often powered by DC voltage and is found in computers, printers, alarm clocks, timers, and other devices. It may produce a variety of sounds, including alarms, music, bells, and sirens, according to the varied designs. Positive and negative pins are the two that are included. This can have a longer terminal or the '+' sign to indicate its positive termination. This terminal draws power from six v ..read more

Electrical energy can be transformed into mechanical energy by an electrical machine called a DC motor. A DC motor uses direct current as its electrical input, which is converted into mechanical revolution. DC motors are favored over other kinds of motors because they can precisely control their speed, which is essential for industrial machines. The ability of DC motors to start, halt, and reverse quickly is crucial for managing the functioning of manufacturing machinery. Construction of a DC Motor The following six components make up a DC motor: Yoke: The outer frame of a DC motor is called ..read more

Introduction A 7-segment display is a type of electronic display that visually represents numerical digits using seven individually illuminated segments. These segments are arranged in a specific pattern to display numbers ranging from 0 to 9. The display consists of seven LED (Light Emitting Diode) or other light-emitting segments, each capable of being independently turned on or off. The arrangement of these segments follows a standard pattern, and each segment is assigned a specific letter or designation. Usually, the 7-segments are identified by the letters a, b, c, d, e, f, and g. By sel ..read more

What is a thermistor? The name "thermistor" is created by combining the words "thermal" and "resistor". As a passive component with temperature-sensitive properties, it is primarily employed as a temperature sensor. A thermistor is a type of resistor that undergoes a significant change in resistance in response to variations in temperature. Every type of resistor exhibits a certain level of temperature dependency, a characteristic encapsulated by their temperature coefficient. Thermistors, specifically, can achieve a high current coefficient. In thermistors, resistance decreases as temperatu ..read more

What is ultrasonic sensor ? An ultrasonic sensor is an instrument or an electronic device that measures the distance to target object using ultrasonic sound waves. It ultrasonic sensor uses a transducer for sending and receiving the ultrasonic pulses which delivers us information about proximity of an object. An ultrasonic sensor transforms the sound reflected to an electric signal. Ultrasonic waves would travel faster compared to the speed of sound which is audible to humans. The ultrasonic sensor has two components namely, transmitter receiver Transmitter uses piezoelectric crystals, the ..read more

What is a hall effect sensor? A hall effect sensor is a type of magnetic sensor used to detect the direction and strength of a magnetic field that is produced from a permanent magnet or an electromagnet, with its output varying in proportion to the strength of the magnetic field that is being detected. A magnetic sensor converts magnetic signals into electrical signals for processing by electronic circuits. A magnetic sensor is a solid-state device. It is becoming popular as it can be used in several different types of applications, such as sensing position, velocity, or directional movement ..read more

What is an accelerometer? An accelerometer is a sensor device or tool that is used to measure the acceleration of an object or a body. It is used to detect the vibration of any structure. Nowadays, accelerometers are found in most cell phones. How does an accelerometer work? An accelerometer is used to detect whether the force is static or dynamic. A constant force that is exerted on an object, namely gravity or friction, is termed static acceleration. These are the kinds of factors that are highly predictable and uniform. For example: The acceleration of gravity is 9.8 m/s and is constant, a ..read more

Introduction In order to connect two places to each other without soldering, jumper wires are just cables with connector pins at each end. To make it simple to modify a circuit as needed, jumper wires are commonly used with breadboards and other prototyping equipment. Although there are many different colors of jumper wires, there is no real significance to the colors. Thus, in theory, a red jumper wire is equivalent to a black one. To distinguish between different kinds of connections, such as power and ground, you may take advantage of the colors. Types of Jumper wires Jumper wires come in ..read more

Introduction A push button switch is a mechanical device that operates by manually pressing a button to activate an internal switching mechanism. Push button switches are used to control electrical circuits. Depending on the needs of the design, they can have a wide range of sizes, forms, and arrangements. Push button switches are crucial components in electrical circuits, often employed in conjunction with various devices such as circuit breakers, relays, and electromagnetic starters. The push button switch is a type of commonly used control switch appliance that is often used to turn on and ..read more
