Скачать или смотреть DIY Automatic Gate Opener with Arduino and Ultrasonic Sensor - Step-by-Step Guide!

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.
