In this project we are going to step down 12 V DC to any DC value between 2 and 11 V. The circuit which steps down the DC voltage is known as buck converter. The output voltage or step down voltage needed is controlled using a potentiometer connected to Arduino. By Ankit Negi INTRODUCTION TO […]

Arduino 2-Step Programmable Timer Circuit
In this article I have explained how to make a simple 2-step Arduino programmable timer circuit, which can be used to switch an electrical load ON/OFF with independently adjustable ON and OFF timings. For example if you want a light to remain ON for 24 hours and OFF for 2 hours, you can simply do […]
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 […]
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 […]
Making an EGS002 Equivalent Board using Arduino
The EGS002 board is nothing but a combination of a microcontroller with a H-bridge driver like the IR2110. So if you are interested to build your own EGS002 equivalent board with exactly identical features, then you can do it using the instructions given in the following article. So, here we are trying to build our […]
How To Use And Program ATmega Microcontrollers From Scratch Without Arduino
ATmega microcontrollers, they are coming from the AVR family which Atmel developed long back, and later this Atmel company was taken by Microchip. So now officially Microchip owns it but still people say Atmel AVR only. These MCUs became very popular slowly because they are easy to understand, quite affordable, stable in long run and […]
