1. Pasang Arduino IDE: Muat turun dan pasang Arduino IDE dari Arduino rasmi webtapak (arduino.cc/ms/perisian).
2. Add ESP32 Board Manager URL: Dalam Arduino IDE, pergi ke File > Keutamaan. In the "Additional Boards Manager URLmedan s", tambah: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
3. Install ESP32 Boards: Pergi ke Alatan > Papan > Pengurus Papan... Cari untuk "ESP32" and install the "esp32 by Espressif Systems" package.
4. Pilih Papan: Selepas pemasangan, pergi ke Tools > Board > ESP32 Arduino and select "ESP32 Dev Module".

5.3. Menghubungkan Lembaga

Connect the ESP32 development board to your computer using a high-quality USB Type-C data cable. Ensure the cable is capable of both power and data transfer.

6. Arahan Operasi

6.1. Basic Programming and Upload

Once your IDE is set up and the board is connected, you can upload your first program.

1. Open an Example Sketch: Dalam Arduino IDE, pergi ke File > Cthamples > 01.Asas > Berkelip to open a simple LED blinking program.
2. Pilih Port: Pergi ke Alatan > Pelabuhan and select the COM port corresponding to your ESP32 board.
3. Upload Sketch: Click the "Upload" button (right arrow icon) in the Arduino IDE. The IDE will compile the code and upload it to the board. During upload, you might need to press and hold the "BOOT" button on the ESP32 board, then press "EN" (reset), and release "BOOT" when the upload starts.
4. Monitor Serial Output: Open the Serial Monitor (magnifying glass icon) to view output from your program. Ensure the baud rate matches your sketch.

6.2. WiFi and Bluetooth Configuration

The ESP32's core functionality lies in its wireless capabilities. Refer to the extensive documentation and examples available for ESP32 on how to configure Wi-Fi in STA (connect to an existing network), AP (create its own network), or AP+STA modes, and how to use Bluetooth Classic or Bluetooth Low Energy (BLE).
