مشروع نظام الامن والانذار باستخدام اردوينو

يتم تنشيط التنبيه في 10 ثوان بعد الضغط على الزر A. للكشف عن الأشياء فإنه يستخدم جهاز استشعار بالموجات فوق الصوتية، وبمجرد أن إنذار كشف شيء ما الجرس يبدأ انبعاث الصوت. من أجل وقف التنبيه نحن بحاجة إلى إدراج كلمة مرور 4 أرقام. كلمة السر مسبقا هي 1234 ولكن لدينا أيضا إمكانية لتغييره.
عن طريق الضغط على زر B ندخل قائمة تغيير كلمة المرور حيث أولا نحن بحاجة إلى إدخال كلمة المرور الحالية من أجل الاستمرار ثم أدخل كلمة المرور الجديدة 4 أرقام. مرة واحدة يتم تغيير كلمة المرور،    سوف تكون قادرا على وقف التنبيه عن طريق إدخال كلمة المرور الجديدة فقط. إذا أدخلنا كلمة مرور خاطئة سوف نحصل على رسالة أننا بحاجة إلى المحاولة مرة أخرى.

المكونات المطلوبة
لوحة Arduino 
 متحسس التراسونيك ultrasonic sensor
شاشة LCD 
4×4 keypad
منبه
