Hello ACC forum,

Finally finished the Matthew project. Thanks to those who answered questions and helped me complete it

Working on new project.
Would like to set a switch in my car where when the door is opened it sounds an alarm
in my house. Sort of like the magnetic switches used for home alarms systems.

There are lots of circuits to set off alarms:
Wireless Doorbell using Arduino and RF Module
But the magnetic switch in the car should activate a radio signal from the car that
would be received in the house and set of a beeper.

Have used Arduino Uno in several projects and am comfortable with them.
But have searched Arduino, Ada Fruit and Sparkfun without success.
