The post helps us to design a relatively simple transformerless 3kva inverter circuit using a full bridge IC network and a SPWM generator circuit. The idea was requested by Mr. Ralph Wiechert   The Circuit request Hi Swagatam, Greetings from Saint Louis...

In this post we are going to construct a circuit which will notify the user via SMS if the water supply to you area / home is initiated. It can show the time when the water is begin to supply and ended, average water flow speed in liter per minute and...

In this post we are going to construct an incubator using Arduino which can self-regulate its temperature and humidity. This project was suggested by Mr. Imran yousaf who is an avid reader of this website. By Girish Radhakrishnan   Introduction This...

In this post we are going to construct a SMS based water pump controller with automatic shutdown of pump when no water flow through the pump is detected.  We will also construct another much simpler automatic dry run preventer circuit without GSM in...

In this post we learn how to make a simple yet useful proximity sensor circuit using a single opamp LM351 and a couple of infrared diodes.   By Navneet Sajwan Introduction A sensor is a device that detects and measures any physical parameter of our environment...
