- Navigate to File > Preferences.
- In the Additional Board Manager URLs field, add the following URL:
- https://dl.espressif.com/dl/package_esp32_index.json
- Click OK.
- Go to Tools > Board > Boards Manager.
- Search for ESP32 and install the latest version by Espressif Systems.
Connecting the ESP32 to Your Computer
Use a micro USB cable to connect your ESP32 development board to your computer. Ensure the drivers are installed correctly, especially on Windows.
Tips:
- Use a good-quality USB cable capable of data transfer.
- Identify the correct COM port or serial port in your system.

Writing Your First ESP32 Arduino Sketch
Basic Blink Program
Start with the classic LED blink example to verify your setup.
```cpp
void setup() {
pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
digitalWrite(LED_BUILTIN, HIGH);
delay(1000);
digitalWrite(LED_BUILTIN, LOW);
delay(1000);
}
```
Steps:
- Select the correct board: Tools > Board > ESP32 Dev Module.
