We have connected an LED to the PWM pin6 of the Arduino board and the analog output ... an arduino and a piece of copper clad board as a rain sensor. This circuit is very easy to make and it also has ...

We have also built a simple Rain Alarm and an automatic car wiper by using 555 Timer only, you might want to check that as well if you do not want to use an Arduino. That being said, let’s get back to ...

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. Aspencore network. ... The goal is now to use a ...

This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

A novel low-cost rain sensor based on a Surface Plasmonic Resonance (SPR) platform has been designed, realized, and tested. The SPR platform has been used to detect the presence of rain by using a ...
