During this project we have designed and built a home alarm. The system have eight digital and three analog inputs.
The analog signals are IR detectors and the digitla signals are from magnetic switches. The alarm have a day and a
night setting, which controls if the analog signals are on or not. The controls to the alarm are an HEX numeric keypad
and a four line alfanumeric screen.
In the report you can read more.
Here are our code.
