I want something like some aftermarket car alarms have, where there is a Keychain fob with a few buttons and a little display. The display will tell you if your alarm is going off or if your door is open, etc.

Instead of connecting to a car alarm I will connect it to an arduino or similar. I do not need a fancy LCD, just a couple of LEDs would work (and a piezo beeper would be nice).
