Automatic Gate keeper Kit

Overview

This DIY project builds an automatic gate. An IR proximity sensor detects an approaching person or vehicle and an Arduino Nano turns a servo to open the gate, with a buzzer confirmation.

How It Works

1. The IR sensor detects an object in front of the gate.
2. The Arduino Nano receives the signal and sounds the buzzer.
3. The SG90 servo rotates to open the gate, then closes it again once the path is clear.

You Will Also Need

A USB-A to USB-C cable to connect the Arduino Nano C-Type to your computer and upload code — not included in this kit.

Applications

• Automatic gates and barriers - hands-free entry models
• Parking demos - a mini parking boom barrier
• Sensor + actuator learning - combine an IR sensor with servo control

FAQ

Do I need coding experience? No prior experience is required - this kit is built around one specific project, and the full code is freely available. See the build guide above.

What tools do I need beyond what's included? A computer with the free Arduino IDE (or ESP8266 board support, where applicable) installed to upload the code. No soldering is required for this build. You'll also need a USB-A to USB-C cable to connect the board — not included.

Can I reuse the parts afterward? Yes - every component in this kit is a standard, reusable part you can use in future projects, not a single-use kit.
