interface gsm module to pic16f877a with password option
this project is ready to use just connect the pin rc6 to recive pin of gsm module , then start the project , \n\nto work with this project follow steps below :\n\n1- if you forget the old password make ( rest password button )lock before start the programe this make password 000000\n\n2- when you access the system by enter the correct pass the system will send you message \" welcom bos \" \n\n3- if you want to reset the password with new one just press * button of keypad tha system will ask you to enter new pass , to complete this operation you must restart muc to reload new pass\n\n4- if you enter the wrong pass for 3 times the system will lock and send alarm message \" some one tray to access our system \"\n\nproject link :\nhttp://www.mediafire.com/download/cuu19x5d3ho5xca/gsm_interface.rar
