Sub-Systems of the MAin Alarm System

Here are the descriptions of the jobs that will be in the Arduino Alarm system.

Door Alarm- This sensor will check if the door that it is hooked on to is open or closed. This piece will need 1 pin, a digital, which can turn something on or something off.

Dust/Smoke Sensor- This sensor will check how much smoke or dust, if there even is any,  is in the air around the sensor. It will require 2 pins, AnalogIn, which can hold different numbers or readings/levels, and a Digital On/Off pin.

Arm/Disarm-  This will be in the program, it is not an actual component, but it will arm the alarm if the A button has been pushed.  It will DisArm if the correct code has been typed on the keypad. It is to change the state of the armed variable. It needs 0 pins.

Panic- This will be a button that automatically sets off the alarm. The function is to check if the button has been pushed or not. It will need 1 pin. Digital On/Off. The program is supposed to set the state of the panic variable.

Motion- This sensor will check for motion in the area. It requires 1 pin. Digital On/Off INput. It's job is to set the motion variable.

Alarm Indicator- This is to activate the indicator, (light Sound etc.) that a sensor has been activated, but it will only go off if the alarm is Armed.  It will  about 4 pins.

Display- The displays job is to produce text and format it  based on the state of the alarm. (Armed DisArmed) . It need 6 pins that are Digital ON/OFF.

Keypad- This is to keep track of the key presses. It is keeping track of the button that has been pushed if a button is pushed. It needs 8 pins, 4 digital input and 4 digital output.


That's all for now!
