The experiment is for switching an acoustic sounder as a rain alarm after a predetermine time. It may, however, be tinkered for a number of other applications. Needless to say, this is a simple ...

A Rain Detection System was developed using Arduino and C++ to provide a cost-effective and scalable solution for smart rain monitoring. The system uses a resistance-based rain sensor module to detect ...

An Arduino-based music project using a distance sensor to measure finger position and play corresponding notes of the 6th guitar string (E). Features a passive buzzer for sound output and an OLED ...

Walking safely and confidently can be a challenging task for visually impaired individuals, but with the help of technology, we can make it easier for them. This DIY Blind Stick is an innovative yet ...

[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]’ ...

Sometimes, it’s time to shut down the oscilloscope, and break out the cardboard and paints. If you’re wondering what for, well, here’s a reminder of an Instructable from [CrazyScience], that brings us ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

Abstract: This study presents a real-time IR distance sensing system for cyber-physical systems (CPS) applications, integrating Arduino hardware control with LabVIEW analytics. The system employs an ...
