About the Project

• Description:

  "This project uses a rain sensor to detect rainfall and automatically drives a motor to oscillate a wiper blade. The motion is smooth and adjustable, mimicking real car wipers. It is powered by Arduino Nano, ensuring compactness and ease of use."

• Key Features:

  • Automatic Rain Detection: Activates only during rainfall.
  • Smooth Wiper Motion: Gradual oscillation between 0° and 90° with speed control.
  • User-Friendly: Adjustable speed and sensitivity for customization.
  • Compact Design: Fits easily into any setup.

• Applications:

  • Automotive industry (smart wipers).
  • DIY projects for automation enthusiasts.
  • Prototypes for weather-responsive mechanisms.

How It Works

• Overview Diagram:

  • A simple schematic showing the rain sensor, motor driver (L298N), Arduino Nano, and wiper motor connections.

• Workflow:

  1. The rain sensor detects water and sends a signal to the Arduino.
  2. The Arduino processes the signal and controls the motor driver.
  3. The motor oscillates the wiper between 0° and 90°.
  4. When the rain stops, the system returns to an idle state.
