Nokia was the most popular mobile phone brand across the globe […]
Make this Simple Weather Station Project for Homes and Offices
In this post I will show how to construct an interesting Arduino based mini weather station project, which can show you ambient temperature, humidity, pressure, air quality and much more data from your surroundings, which can be used to predict weather from home. If you are interested in meteorology this project might come in handy […]
Arduino Frequency Meter Using 16 x 2 Display
In this article I will show how to construct a digital frequency meter using Arduino whose readings will be showcased on a 16 x 2 LCD display and will have a measuring range from 35 Hz to 1MHz. Introduction Being electronics enthusiast, we all would have come across a point where we need to measure […]
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 […]
