In this post we elaborately study how to make an Arduino based PWM signal generator circuit, which can be set or adjusted with a potentiometer or a pot to any preferred duty cycle ratio. By Ankit Negi WHAT IS PWM? pwm or pulse width modulation as the name itself suggest is modulation of width of […]

How Blocking Oscillator Works
A blocking oscillator is one of the simplest form of oscillators which is able to produce self sustaining oscillations through the use of just a few passive and a single active component. The name “blocking” is applied due to fact that the switching of the main device in the form of a BJT is blocked […]
Automatic Street Light Dimmer Circuit
In this post I will show how to construct an Arduino automatic street light dimmer circuit, which can reduce its brightness when no vehicle is passing in the road to save power. By Overview We will be exploring the methodology of sensing the vehicle or human being without false detection which may occur due to […]
Induction Heater for Labs and Shops
In this post I have explained how to make small homemade induction heater circuit for laboratories and shops for carrying out small scale heating jobs such as melting ornaments, or boiling small quantity of liquids using electricity or battery The idea was requested by Mr. Suni and Mr. naeem Circuit Objectives and Requirements Our challenge […]
Arduino Modified Sine Wave Inverter Circuit
In this post I will show how to construct a modified sine wave inverter using Arduino. We will explore the methodology of the proposed sine wave inverter and finally, we will take a look at simulated output of this inverter. By Difference Between Squarewave and Modified Squarewave Inverter Inverters saved us from short term power […]
Single LM317 based MPPT Simulator Circuit
To make this simple MPPT circuit we first modify a standard LM317 power supply circuit into a buck converter then configure it with a solar panel for implementing an MPPT function. Modifying a LM317 Power Supply into an MPPT Solar Optimizer In our previous article I have explained how a standard LM317 power supply could […]
