This BQ24295 IC is like a super smart charger chip. This one is not just for charging battery, but also doing many other jobs like boost converter, USB detection, power path control, and even OTG (host power supply). So we can say that this is a full battery charging and power management IC. Let us […]
Newly Updated Circuit Projects:
Arduino SPWM Generator Circuit – Code Details and Diagram
In this post I have explained how to generate sine wave pulse-width-modulation or SPWM through Arduino, which can be used for making a pure sine wave inverter circuit or similar gadgets. The Arduino code is developed by me, and it is my first Arduino code, …and it looks pretty good 🙂 What is SPWM I […]
H-Bridge Sine Wave Inverter Circuit using Arduino
In this article I will explain how we can build an Arduino-controlled H-Bridge sine wave inverter circuit using some easy parts. So this thing will basically convert DC into AC but in a way that looks like a sine wave, right? We are using an Arduino to generate PWM signals and these signals will drive […]
Arduino Pure Sine Wave Inverter Circuit with Full Program Code
This article explains a simple pure sine wave inverter circuit using Arduino, which could be upgraded to achieve any desired power output as per the user’s preference. Circuit Operation In the last article I have explained how to generate sine wave pulse width modulation or SPWM though Arduino, we are going to use the same […]
Real MPPT Solar Charger Circuit Using Arduino, LCD, and Manual/Auto Switch
So in this article we are trying to make a true MPPT solar charger project using Arduino which will charge a 12V battery from a solar panel and will use MPPT logic to always extract maximum power from the solar panel. That means that even when sunlight changes, we try to adjust PWM duty cycle […]
AC Motor Speed Controller Circuits using Back EMF
In this post I have explained a few circuit diagrams for building AC motor speed controller circuits using back EMF concept. Working Principle of AC Motors So now, all those home type appliances like electric drill machines, sander machines, sewing machines, food mixer machines, etc. they all are mostly using that AC motor which is […]
