Summary
Well, this has been a bit of a mix-and-match of various topics to end on before we put together our home security system framework. I hope you enjoyed these various footnotes to previous chapters, and that it's given you some ideas on how far you can take your home security system.
We started by looking at ways we can arm and disarm our system without having to access the Web-based control panel, by adding a mechanical or digital switch to an arm/disarm input.
We then looked at adding analogue-type sensors to our system, which can alert us when a threshold has been reached by using operational amplifiers set up as voltage comparators. The idea behind these comparator circuits can be implemented for different types of sensors where you want ...
