Automatic Hand Sanitizer Circuit – Fully Contactless
In this article I have explained how to make a low cost yet fully automatic hand sanitizer dispenser circuit which will allow a touch-free or contactless dispensing of the sanitizing liquid on the user’s hands. This contactless hand sanitizer circuit facilitates the user to access the sanitizing liquid on hands automatically without the need of […]
Gadgets to Protect Women from Assaults and Harassment
Gadgets and devices that are specially designed to repel or deter a potential male offensive can be used by a girl to protect herself from a crime situation, and therefore can be very handy. In this post I have explained a few of these devices which could be either purchased or even developed at home. […]

Car Reverse Parking Sensor Circuit with Alarm
In this post I will show how to construct a car reverse parking sensor alarm circuit using arduino, ultrasonic sensor and 2.4 GHz transceiver module. This project can be add-on feature for your car if it doesn’t sport a build-in parking sensors. Introduction The proposed project has similar functionality as traditional car parking sensor has, […]
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. By Overview We will be exploring the methodology of sensing the vehicle or human being without false detection which may occur due to […]
