קורס אמבדד – RB19-08 מבוא למיקרובקרים – בקרת מנוע , שימוש בבינה מלאכותית

שיעור זה נתרגל מחרוזות “שיפעלו” אלקטרוניקה , שלמדנו בהרצאות קודמות .

תרגיל כיתה : בניית קוד תוכנה עלי די בינה מלאכותית

0. תרגיל כיתה בנה תכונה ב chatGPT – יש לבקש – להקליד מהבינה מלאכותית הכל בשפה האנגלית

0.1 יש לכתוב במפורש את הבמילים “esp32 Arduino code”

0.2 פין 2 מחובר ללחצן שמוגדר ב PULL UP

0.3 כאשר נלחץ על הלחצן button נשלחת הודעה לטרמינל – לחצן נלחץ

0.4 הרץ את המעגל ב wokwi לפי הקוד של הבינה מלאכותי

0.5 בקש מהבינה מלאכותית להוסיף לד , כאשר הכפתור נלחץ נלדק גם לד – בנה והרץ תוכנית

0.6 בצע מספר שגיעות בקוד , העתק את הקוד ובקש מהבינה המלאותית לתקן את הקוד FIX CODE ואז הוסף באותו שיחה את הקוד .

תרגיל כיתה – חזרה על מחרוזות

הרץ את הןד הבא בסביבית WOKWI הוסף לד ונגד לפי הצורך – Serial.readStringUntil(‘\n’)
