קורס RB10 , רובטיקס בלוקס : תרגול 009 – רמזור מעבר חציה UART esp32
תכנות רמזור מעבר חציה למכוניות – ושער משמרות זהב
1.שלב ראשון נבנה רמזור למכוניות ושער להוכלי רגל – תוכנית פשוטה
לתכונית יש מספר בגים ונשפר אותה בשלב השני .
התחלת התוכנית – מצב קמזור למכוניות ירוק – לילדים שער סגור
2.לחיצה על כפתור ירוק – פתיחה
3.לחיצה על כפץור ירק – סגירה

4. באלגוריתם התוכנה והמערכת קייים מספר בגים מה הם ?
רמז: (בדוק מה קורה אם לוחצים על הכפתור האדום בהתחלה במקום הירוק)
תוכנה לאחר תיקון הבאג
