السلام عليكم
انا عضوة جديدة ومحتاجة مساعدتكم بخصوص موضوع مهم جدا
انا عندي مشروع مهم جدا وتعطل الى الان لانه محتاجة اعرف طريقة عمل ريموت كنترول مفتاح السيارة وانا اجهلها.
لوسمحتوا الله يعافيكم اي احد عنده افادة بخصوص الموضوع ياليت يساعدني ولكم جزيل الشكر .

the car remote control works as follows:
the remote issues a sound wave not an electric wave
this sound wave is in the ultra-soundn range
that is: it is frequency is > 20khz
each command on the remote control has a specific sound wave format
and when this sound is sent from the remote control the the receiver located at the car recieves this wave and intreprets (understands) it as the commans being issued by the remote control
this sound wave is not an electrical wav and its frequence is >20khz and is samll sa well
this enables this wave to propagate over relatively short distances and enables it to propagate through the walls and any other reflectors that may exist in its way.
is this explanation enough?
if ok send me an email mustafa_arra(at)yho
