التحكم في الوصول إلى الباب / قفل الباب RFID مرحبا بالعالم! اليوم صنعت قفل باب RFID. المصباح بمثابة قفل باب كهربائي لأنني لا أمتلك قفلًا كهربائيًا ، يمكنك ببساطة إضافة قفل الباب إلى المرحل بدلاً من المصباح. تحقق من الرابط الخاص بقائمة التعليمات البرمجية والأجزاء التخطيطية. لم أتمكن من العثور على الكثير عن الوحدة ، لدي RFID-RC522 باللون الأزرق ، لذلك قد يكون هذا مفيدًا لأولئك الذين لديهم نفس المشكلة مثلي لأن اللون الأحمر يحتوي على دبابيس مختلفة ... .. إذن هنا هو الكود الصحيح والتخطيطي .. إنه يعمل بشكل جيد! ما عليك سوى توصيله مثل التخطيطي ، وتحميل الكود ويجب أن يعمل. rfid , project, robot, ms project,gantt project يوجد زر لمسح قاعدة البيانات. كيف يعمل هذا بسيط ، ما عليك سوى الضغط على الزر وإعادة تعيين اردوينو. احتفظ به لمدة 6 ثوانٍ وسيؤدي إلى مسح جميع البطاقات المضافة. بعد ذلك تحتاج إلى إضافة بطاقة رئيسية وبطاقات مفاتيح جديدة.
