Abstract


The title of this nal
report is the use of IC 27C010 Sound On Indicators For
Automatic Door System With Microcontroller AT89S51.
The main purpose of making this thesis is how to integrate
IC 27C010 As Indicators of Sound with Microcontroller
AT89S51 In System Simulation Automatic Door. The way
it works is when we enter the current in the circuit then
there will be display on the LCD "ACCESS DOORS" and
there are LED indicators that light up red means the cir-
cuit in a state of the closed door, then press "* (star)" on
the keypad to enter the password would be no LCD display
on the "Password:", which we input the code by pressing
the keypad. code has been entered will be read and fed to
the microcontroller to be stored and processed. If the code
has been registered or is true, then there is a LED indica-
tor that lights up green colored LCD will then display the
"Open Door" and when doors open IC 27C010 is a sound
indicator function that will read "Please Login" along with
the door open and moved by DC motors and there are LED
indicators that light green colored. Then IC 27C010 will
serve to remove voice "Please repeat" if the code is wrong
or not registered. then there is a LED indicator that lights
up yellow colored if the password is wrong to 3 times the IC
voice will sound "you are not allowed to enter" and the LCD
will display "Wrong Password"
