Getting Started

Environment Setup

Follow these steps to prepare your development environment before the training.

Step 1

Install Arduino IDE

Download and install the latest Arduino IDE for your operating system.

Download Arduino IDE
Step 2

Install USB Drivers

Install the CH340 or CP210x driver so your computer can recognize the ESP32 board via USB.

CH340 Driver CP210x Driver
Step 3

Add ESP32 Board Manager

In Arduino IDE, go to File → Preferences and paste this URL into Additional Board Manager URLs:

https://dl.espressif.com/dl/package_esp32_index.json
Step 4

Install ESP32 Board Package

Go to Tools → Board → Boards Manager, search for esp32, and click Install.

Then select ESP32 Dev Module from the board list.

Step 5

Install Blynk Library

Go to Sketch → Include Library → Manage Libraries, search for Blynk, and install "Blynk by Volodymyr Shymanskyy".

Step 6

Install Blynk IoT App & Open Web Dashboard

Download the Blynk IoT app on your phone. For desktop control, use the Blynk Web Dashboard directly in your browser.

Hardware Reference

ESP32 Pin Mapping

Complete GPIO assignments used throughout the training curriculum.

Component ESP32 Pin Type Code Reference Session
5V Relay (Pump) GPIO 5 Digital OUT #define RELAY_PIN 5 3.2, 4.1
DHT11 (Temp/Humidity) GPIO 4 Digital IN #define DHTPIN 4 3.4, 4.1
Flame Sensor (KY-026) GPIO 14 Digital IN #define FLAME_PIN 14 3.4
Active Buzzer GPIO 12 Digital OUT #define BUZZER_PIN 12 3.4
Soil Moisture Sensor GPIO 34 ADC1 (Analog) #define SENSOR_PIN 34 3.3, 4.1
LDR (Light Sensor) GPIO 35 ADC1 (Analog) analogRead(35) 4.1
⚡ Important Notes
  • Power: Always power 5V Relay from VIN, never from 3.3V pin — prevents brownouts.
  • ADC: ESP32 has 12-bit resolution (0–4095). GPIO 32–39 are ADC1 pins, safe to use with WiFi.
  • GPIO 12: Bootstrap pin — starts LOW by default, so no boot issues with buzzer. GPIO 13 is a safe alternative.
