3. Οδηγίες λειτουργίας

3.1. Uploading Your First Program (Blink LED)

A common first step is to upload a simple program to make an LED blink.

1. Connect ESP32: Connect your ESP32 board to your computer using the Micro USB cable.
2. Επιλέξτε πλακέτα και θύρα: Στο Arduino IDE, μεταβείτε στο Εργαλεία > Πίνακας and select the appropriate ESP32 Dev Module. Then, go to Εργαλεία > Θύρα and select the serial port connected to your ESP32.
3. Ανοίξτε π.χampτο Σκίτσο: Μεταβείτε στο File > Π.χamples > 01.Βασικά > BlinkΑυτό θα ανοίξει ένα νέο παράθυρο με το σκίτσο Blink.
4. Μεταφόρτωση: Click the "Upload" button (right arrow icon) in the Arduino IDE. The IDE will compile the code and upload it to your ESP32 board. If prompted, press the BOOT button on the ESP32 board during upload.
5. Παρατηρώ: After successful upload, the built-in LED on the ESP32 board should start blinking.

6. Αντιμετώπιση Προβλημάτων

Εάν αντιμετωπίσετε προβλήματα, λάβετε υπόψη τα ακόλουθα βήματα αντιμετώπισης προβλημάτων:

• Μη Αναγνωρισμένο Διοικητικό Συμβούλιο:
  • Ensure the Micro USB cable is a data transfer cable, not just a charging cable. Some cables only provide power and cannot establish a data connection.
  • Check if the correct USB driver is installed for the ESP32's USB-to-Serial chip (often CP210x or CH340).
  • Verify the correct serial port is selected in the Arduino IDE.
• Code Not Compiling/Uploading:
  • Check for syntax errors in your code.
  • Ensure all necessary libraries are installed.
  • During upload, you might need to press and hold the ΜΠΟΤΑ button on the ESP32 board, then press the EN (reset) button, release EN, και στη συνέχεια απελευθερώστε ΜΠΟΤΑ.
• Το στοιχείο δεν λειτουργεί:
  • Double-check all wiring connections against the tutorial diagrams. Ensure correct polarity for LEDs and other polarized components.
  • Verify the component is receiving adequate power.
  • Ensure the correct code and pin assignments are used for the specific module.
  • Test with a known working component if possible.
• Θέματα ισχύος: Ensure your power supply is stable and provides the correct voltage (5V for the ESP32 board).
