Home alarm system

7. Errors/Could Do betters
:: 7.1 Introduction
The complete system worked fine, almost from first time. But certain parts in the design maybe could have been done better. I will not make a second version of the system, because there always will be something that could have been made better. Besides, if the alarm is triggered ... it's already too late: someone is in your house...

:: 7.2 Could do betters list

auto battery recharge system
more powerful battery
more powerful diodes
I²C output for future expansion
siren activated by closing +12V line instead of GND
certain protocol for code lock, instead of ON/OFF pulse
other code lock that doesn't allow wrong codes
alarm trigger when case is opened
polling zone inputs
more sabotage detection
