Build an Arduino-based smart helmet with RF transmitter & receiver featuring theft, wear, alcohol, and drowsiness detection. Simple DIY project with easy-to-follow circuit diagrams, code, and ...

This paper aims to build a framework for keeping the vehicle protected and shielding it by the intruder's occupation. When running by less conscious we cannot take care of our own. When we do all the ...

The purpose of this paper is to develop a system that can effectively detect alcohol. A hygienic way of detecting alcohol has been developed. An MQ-3 sensor is connected to an Arduino Uno board which ...

The researchers used an Arduino Uno board, an Adafruit LCD, a desk fan and a household spray bottle to transmit a short message across a tabletop, via molecular diffusion.

With all the hands-free dispenser designs cropping up out there, the maker world could potentially be headed for an Arduino shortage. We say that in jest, but it’s far too easy to use an Ardu… ...
