3v, 4.5v, 6v, 9v, 12v, 24v, Automatic Battery Charger Circuit with Indicator
An all-in-one automatic voltage battery charger circuit is discussed in the following post; the circuit can be modified in many different ways as per individual requirements and applications. The following circuit will allow you to charge any battery right from 1.5V to 24V simply by setting up a given preset. How it Works using LM3915 […]
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 […]
Arduino Automatic School/College Bell System
In this post I will show how to construct an automatic school bell/college bell system using Arduino, 16 x 2 display and real time clock module. You can program this project to ring the bell up to 16 times a day at your preferred hour and minute. The length of the bell ring can be […]
Automatic Street Light Dimmer Circuit
In this post I will show how to construct an Arduino automatic street light dimmer circuit, which can reduce its brightness when no vehicle is passing in the road to save power. Overview We will be exploring the methodology of sensing the vehicle or human being without false detection which may occur due to animals […]
Automatic Door Circuit using PIR – Touchless Door
Along with social distancing and masks, the other major thing the post COVID-19 era has compelled the world to implement is to go touchless. This is being recommended for the many public devices, such as doors, hand sanitizers, buttons, switches etc. in order to restrict the spread of viruses that may be caused due to […]
