Class B Amplifier
To improve the full power efficiency of the previous Class A amplifier by reducing the wasted power in the form of heat, it is possible to design the power amplifier
Thermistor Based HVAC Thermostat
In this blogpost, we will discuss about thermistor based HVAC Thermostat. The functions of heating, ventilation and air conditioning are often combined into one system in today’s homes, offices and buildings
Arduino MCP2515 CAN Bus Interface Tutorial
Introduction Controlled Area Network of simple CAN is a bus standard that allows a Microcontroller and its peripheral devices to communicate without the need of a host device or a
Arduino DC Motor Control using L298N Motor Driver
In this project, we will see how to control a DC Motor using Arduino and L298N Motor Driver. There are different ways to control a DC Motor but the Arduino
12V DC to 220V AC Converter [Tested Circuit]
In this tutorial blog, we will look into the circuit architecture to convert 12V DC to 220V AC power. This is a tested circuit so you will have no problem
Twin-T Oscillator
Twin-T Oscillators are another type of RC oscillator which produces a sinewave output for use in fixed-frequency applications similar to the Wein-bridge oscillator. The twin-T oscillator uses two “Tee” shaped RC networks in
Bluetooth Controlled Robot using Arduino
In this project, I will show you how to design and develop a Bluetooth Controlled Robot using Arduino, HC-05 Bluetooth Module and L298N Motor Driver Module. On the other end
How to Enable ESP8266 Deep Sleep Mode? Timer Wake-up
In this tutorial, we will lean about the Low Power operations of ESP8266 SoC and also learn how to enable ESP8266 Deep Sleep Mode. We will also measure the current
Op-amp Multivibrator
The Operational Amplifier or Op-amp for short, is a very versatile device that can be used in a variety of different electronic circuits and applications, from voltage amplifiers, to filters, to signal conditioners. But
Input Interfacing Circuits
Interfacing is the method of connecting or linking together one device, especially a computer or micro-controller with another allowing us to design or adapt the output and input configurations of the
The Autotransformer
Unlike the previous voltage transformer which has two electrically isolated windings called: the primary and the secondary, an Autotransformer has only one single voltage winding which is common to both sides. This
Electrical Relay
Thus far we have seen a selection of Input devices that can be used to detect or “sense” a variety of physical variables and signals and are therefore called Sensors. But there are
