PEMBUATAN PROGRAM PADA SISTEM KEAMANAN PINTU GESER DENGAN MENGGUNAKAN READS51

Abstract

a program can apply for security control at door shift with automatic for open and closing door with password, LCD display and also equipped with alarm has been made. This system use IC Microcontroller AT 89S51 and use language assembly “Reads51”as foundation program from Intel also use AEC-ISP for filling in code to the chip. This instrument aplicated 3 censor of limit switch for open and close door shift and for alarm too, limit switch 1and 2 use for control open and close door shift where this limit switch will give pulse to microcontroller through program to stop motor DC rotation when door shift touch of limit switch. While limit switch 3 for control security if door will open with force and then will sounding alarm. This security system at shift door have a control program covering initialitation LCD program, driver keypad, including password input, input password, change password also alarm control. Equipped with to change password and control alarm so that security at the door shift can always protected.
