Simple Wireless Power Transmission Circuit to Glow an LED
The Wireless Electricity Transfer concept is not new. It was first demonstrated by Nikola Tesla in the year 1890. Nikola Tesla introduced electrodynamics induction or resonant inductive coupling by lighting up three light bulbs from the distance of 60 feet from the power source. We have also built a Mini Tesla Coil to transfer the energy.

Different Types of Transformers and Their Applications
A transformer is a widely used device in the electrical and electronics domain. It is an electromagnetic device which follows the basic principle of electromagnetism discovered by Michael Faraday. We have covered about Transformers construction and operation in detail in previous tutorial. Here we will cover different types of transformers used in different types of applications. However, all types of transformers follow the same principles but they have different construction method.

Brushed vs Brushless Motors

The requirement for DC motors differs from one application to the other, as one application may require more torque and reduce speed while another may require more speed and reduced torque, thus DC motors are sometimes classified by sales folks based on this.

What is PWM

While ADC is used to read Analog signals by a digital device like microcontroller. A PWM can be considered as an exact opposite of it, PWM is used to produce Analog signals from a digital device like microcontroller. In this article we will learn about what is PWM, PWM signals and some parameters associated with it, so that we will be confident in using them in our designs.

Arduino Relay Control

Whenever we need to connect any AC Appliance in our embedded circuits, we use a Relay. So in this arduino relay control tutorial we will simply learn How to interface a Relay with Arduino. Here we are not using any Relay Driver IC like ULN2003 and will only use an NPN transistor to control relay.

Different Types of Switches and Their Applications

There are mainly two types of switches- mechanical switch and electrical switch. Mechanical switches require physical or manual contact with switch for operation. Electrical switches not require physical or manual contact, it has ability to perform operation. Electrical switches operate under the action of semiconductors.
