Creating a Melody Program
A simple buzzer can be connected to the ESP32 controller for producing sound. It can also be used to produce melodies. In this article, using two different examples, the C code is used on Arduino to make the buzzer play the melody. In the first example, “Twinkle Twinkle Little Star”, the poem’s notes are played and in the second example, another famous poem “Jingle Bell” is used for playing the note while making two colored LEDs on and off to create a light show with music. Example 1: Playing the poem notes using buzzer and ESP32 The circuit is made ...
Read MoreDifference between Analog and Digital Multimeter
A multimeter is a multipurpose electronic measuring instrument extensively used by professionals to determine the faults in a circuit. A typical multimeter can be used to measure various electrical quantities such as voltage, current, resistance, transistor gain, etc.Based on the design and method used for the measurement, multimeters are classified into two types −Analog Multimeter (AMM)Digital Multimeter (DMM)The various differences between an analog multimeter and a digital multimeter are shown in the table below. We have also included a brief description on analog and digital multimeters.What is an Analog Multimeter?An analog multimeter is a type of multimeter which displays the ...
Read MoreDifference between CVT and UPS
There are two different technologies namely, CVT (Constant Voltage Transformer) and UPS (Uninterrupted Power Supply) that are used for providing power conditioning and protection. A CVT is an electrical device used to provide a constant output voltage despite variations in the input voltage or load, whereas a UPS is an electronic device used to provide power during power outages and voltage fluctuations. Read this article to learn more about CVT and UPS and how they are different from each other. What is a CVT? A CVT is an electrical device that is used to provide a constant and stable ...
Read MoreDifference between VA and Watts
Volt-Ampere and Watts are power measurement units. Volt-ampere is used to measure the total power that is being consumed by a device. Watts is used to power the device so it can perform its useful work. The product of voltage and current in an AC (alternating current) circuit is known as a unit of apparent power, or VA. It shows the overall power used by a device, which includes both the useful power used and the power lost as a result of inefficiencies like reactive power. The real power used by a gadget to carry out productive work is measured ...
Read MoreDifference between Cooler and Air Conditioner
Air coolers and air conditioners are popular electronic appliances that help cool down a room’s temperature. But these two appliances operate in completely different ways and provide different set of features. A cooler is also known as an evaporative or air cooler, which generally works by pulling in the hot air from the room and passing it over the wet pads, where it causes the water to evaporate and cools the air. The air that has been cooled is now circulated back into the room by lowering the room temperature. Coolers are more energy efficient comparing it to the air ...
Read MoreDifference between Amplifier and Receiver
An amplifier is an electronic device that is used to amplify an electrical signal without changing its other properties. It is used to amplify audio signals so that they can be played through loud speakers. It can be integrated into other appliance like a receiver or a home theatre system. A receiver is a multi-functional electronic device that combines the functions of an amplifier and a tuner. It is the home theatre system's central control unit, responsible for receiving and processing audio and video signals from various sources such as cables, satellite boxes, and Blu-ray. These signals are received by ...
Read MoreDifference Between Electromotive Force and Magnetomotive Force
The magnetomotive force is analogous to the electromotive force in an electric circuit. If an electric circuit's electrons are being propelled by an electromotive force (EMF), then the magnetic flux or field lines are being propelled by a magnetic field force (MMF). What is Electromotive Force? The passage of electrons in an electrical circuit is propelled by electromotive force (EMF). The presence of an electrical charge creates a field surrounding it, which may either attract or repulsion other charged particles. A potential difference is produced when enough of these charged particles are separated. Electromotive force is the difference in ...
Read MoreDifference between LVDS and TTL
The distinction between LVDS and TTL would be that LVDS relates to information transmission mode, whereas TTL refers to suitable transmission. In LVDS, two wires with various voltages are used, while TTL uses a ground system reference to identify the presence or absence of voltage in digital digits of 0 or 1. LVDS requires around 350mV of power. Because LVDS has excellent resistance to distortion, gadgets can use length wires. Twisted pair copper wires are employed in LVDS to produce strong electromagnet coupling. They have the capacity to stabilize voltage spikes. In contrast to TTL, the third point of reference ...
Read MoreDifference between Electric Field and Magnetic Field
There is a property of space which is caused by the motion of the electric charge, is known as electromagnetic field. There are two component of an electromagnetic field viz. −Electric fieldMagnetic fieldA stationary electric charge produces only an electric field in the surrounding space. If the electric charge is moving, then it also produces a magnetic field. The electric field and magnetic field occupy different planes relative to the cause of the electromagnetic field, i.e., moving charge.Therefore, one of the major difference between electric field and the magnetic field is that the electric field produces around a static electric ...
Read MoreWhat is Voltage Regulator 7805 – Internal Block Diagram and Applications
In this article, we will discuss the definition, internal block diagram, circuit configuration, and applications of voltage regulator 7805 IC. Let’s begin with the basic introduction of voltage regulator. A voltage regulator is an essential element of power supplies used in several electrical and electronic devices such as computers, amplifier, automobile alternator, mobile chargers, etc. A voltage regulator is basically an electronic circuit that generates a regulated voltage of fixed value from an unregulated fluctuating voltage. A voltage regulator is required in a circuit because all voltage sources cannot provide a steady voltage due to change in the load current ...
