🐶 Smart IoT-Based Pet Feeder using ESP32 + Servo + Dashboard Control

📌 1️⃣ Introduction of the Project

The Smart IoT-Based Pet Feeder is an automated feeding system designed to feed pets remotely using the Internet.

This project uses an ESP32 microcontroller, a servo motor, and an IoT dashboard to control and monitor the food gate of a pet feeder from anywhere in the world.

With this system:

• The user can open or close the food gate remotely.

• The dashboard displays the real-time status of the gate.

• Feeding can be controlled even when the owner is not at home.

This project solves the problem of:

• Busy schedules

• Forgetting feeding time

• Traveling situations

• Remote pet care

It is a combination of:

• Embedded Systems

• IoT (Internet of Things)

• Automation

📌 2️⃣ Objective of the Project

The main objectives are:

• ✅ To design a remote-controlled pet feeding system

• ✅ To control the food gate using IoT

• ✅ To display feeding status (Open/Close)

• ✅ To automate feeding from anywhere

📌 3️⃣ Components Required

📌 4️⃣ Use of Each Component

🔹 1. ESP32

The ESP32 is the brain of the project.

Uses:

• Connects to WiFi

• Communicates with IoT dashboard

• Controls servo motor

• Sends status updates

Why ESP32?

• Built-in WiFi

• Fast processing

• IoT compatible

🔹 2. Servo Motor (SG90)

The servo motor is used to control the food gate.

Working:

• 0° → Gate Closed

• 90° → Gate Open

Why servo?

• Precise angle control

• Easy to program

• Low power consumption

🔹 3. IoT Dashboard (Blynk)

We use the Blynk IoT platform.

Purpose:

• Button to Open/Close gate

• Display status LED

• Control from anywhere

• Real-time monitoring

🔹 4. External Power Supply

Why required?

• Servo motor draws more current.

• ESP32 alone cannot safely power servo.

• Prevents reset problem.

📌 5️⃣ Circuit Connection

🔌 Servo Connections

🔌 Important:

⚠️ Connect ESP32 GND and External Supply GND together

Common ground is very important.

📌 6️⃣ Working of the Project

1. ESP32 connects to WiFi.

2. User opens Blynk dashboard.

3. Presses “Feed” button.

4. Command sent to ESP32.

5. Servo rotates to 90°.

6. Food gate opens.

7. Status LED turns GREEN.

8. After few seconds servo returns to 0°.

9. Gate closes.

10. Status shows CLOSED.

📌 7️⃣ Features of This Project

• 🌍 Remote control from anywhere

• 📱 Mobile dashboard

• 🔄 Real-time status update
