DIY Arduino Gate Opener with Ultrasonic Sensor 🚪

Welcome to **RR Techs!** In this tutorial, we’ll show you how to build a simple **Automatic Gate Opener** using a proximity sensor and a servo motor. This project allows gates or doors to open automatically when motion is detected, offering a hands-free, convenient solution.

#### Components Required:
- **Arduino** (e.g., UNO or Nano)
- **Servo Motor** (for gate movement)
- **Proximity Sensor** (IR or Motion Sensor)
- **Jumper Wires & Breadboard**

#### How It Works:
1. The **sensor** detects a person or object and sends a signal to the Arduino.
2. If someone is detected, the **servo motor** opens the gate by moving to 0°.
3. After 2 seconds, the servo moves to 270° to close the gate.
4. If no one is detected, the gate stays closed at 180°.

#### Key Features:
- **Hands-Free Operation**: The gate opens automatically when someone approaches.
- **Efficient Design**: Uses a sensor and servo for simple control.
- **Power-Saving**: The servo only moves when necessary.

#### Applications:
- **Home Automation**: Automatic gates for homes or businesses.
- **Touch-Free Systems**: Reduces the need for physical contact.
- **Access Control**: Ideal for security gates, parking barriers, and more.
