This project for Rain Detector Circuit using Arduino shows how to detect rain, here, rain sensor plate feels water drops. Then, the module gives analog and digital signals, and the Arduino reads these signals and finally, the LED glows when it starts raining. Therefore, this low-cost project is easy for beginners to build. Arduino Code: […]
