Raindrop Detector

Introduction: Raindrop Detector

I used this person's idea (https://www.instructables.com/id/Arduino-Modules-Rain-Sensor/ )of making the raindrop project. I add a LED when the detector detects water on the surface.


- MH-RD Raindrop Module

- Wires


- Arduino Leonardo

Step 1: Step 1: Programing

I added the program of the LED blink on the bottom as you can see. Also, when the Detector touches water, the LED will blink. If not, the LED wouldn't blink.

My code :https://create.arduino.cc/editor/alan5945/74961d46-5eb6-470b-a191-f361c1b27d41

Step 2: Step 2: Making the Detector

Place the orange wire to A0

Place the Yellow wire to the GND

Place the green wire to the 5V

Place the LED with positive and GND.

Step 3: What Can You Use It For

You can use it for knowing when it is raining and also for cars. When the detector detects the raindrops, they can help the driver the open the wipers.
