Nokia 3310 screen already had several applications with bi-color LCD at this time I decided to experiment with it. Heavily on the market, the Nokia 6100 LCDs and their controllers for microchip using Atmel ATmega8 given codes can edit and work with Winavi made to optimize and tried with ATmega8 code works just fine.
220Ω, and 330Ω with ATmega8 voltage divider screen I used to drive. But who wants to run ATMega8 3.3 volts without the use of resistance can take the screen. Including 8-bit and 12-bit color display mode has two 8bit color I did with trials. Drivers in the file by writing to the screen, draw various geometric shapes and functions available in press bmp image. All the files associated with the application can be accessed from the link below.

Central Security System with pic16f877
Circuit Operation: PIC16F877 used in the circuit of the B and D as input port is selected. 8 of these units with port B doors, windows and etc.. from places logic 1 or 0 state is evaluated. D port is necessary for system operation or stopping the input of a predetermined password has been supplied. A and C are chosen as output port with port status LEDs and alarm circuit has been. C port to the B port is where you get the warning from the 7 segment LED display is used as the indicator showing. Instead of port 1 LED alarm circuit 1 or 0 is used to determine whether, enter the password warning LED LED 2, 3 the password is correct, and that LED LED LED yandıkd 4 seconds after the system is activated. 4 LED lights up when the system stops enter the password.
