Generally it is noticed that while charging batteries people hardly pay any special attention toward the procedures. For them charging a battery is simply connecting any DC supply with matching voltage with the battery terminals. A fast battery charger circuit charges a battery with enhanced speed so that it is charged in less time than the specified period. […]

Automatic Vehicle Headlight Dipper/Dimmer Circuit
The circuit described here can be built and used in your vehicle for an automatic dipping and dimming operation of the vehicle headlamps, in response to the intense lights coming from an opposite vehicle headlamps. What’s a Dimmer/Dipper in Automobiles An automobile headlight dimmer/dipper is a circuit which automatically switches the headlight intensities of vehicles arriving from […]
SMS Based Pump Controller with Automatic Dry Run Shut Off
In this post I will show how 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 the next half of the article. What is Dry Run in […]
7 Automatic Street Light Circuits [Using Relays and Solar Panel]
In this article I will elucidate 7 useful yet simple automatic street light circuits using 220 V relays and solar panel. All the presented circuits can be used for automatically switching a lamp ON during night time and OFF during day time. What is an Automatic Street Light System An automatic street light system is […]
Automatic Irrigation Circuit using Arduino
In this post I will show how to construct an automated water irrigation system for small garden using arduino and soil moisture sensor. Introduction The proposed system can monitor the soil moisture level and when soil moisture goes below preset value, the 12V DC pump will be triggered for predetermined period of time. The status […]
Incubator Using Arduino with Automatic Temperature and Humidity control
In this post I will show how 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. Introduction This project was designed as per the suggestions from Mr. Imran, but some additional modification is done to […]
