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 […]

DHT11 Humidity, Temperature Sensor: How to Use and Interface with Arduino
We are now going to talk about one small cheap sensor that we call DHT11, and we can use that for measuring humidity and also temperature. You can see that many Arduino people like this sensor because it is very simple and also very low cost, so anybody can buy and try. The DHT11 can […]
100A AC Load Monitoring Circuit using Arduino, Watt Limit, LCD, Alarm, Auto Shutdown
In this project we are going to make one very useful grid power protection circuit. This will be like a power guard system which we can use in homes or apartments to monitor the wattage of the load and also to cut off the load automatically if it starts taking too much wattage, more than […]
Replicating 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 […]
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 […]
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 […]
