M2M Demo – Lesson #13 : Camera Alarm System
In this final tutorial you build your very own alarm system by composing a setup of some of the parts you got to know throughout the lessons. You built an alarm system triggered by a self-built IR light barrier. The alarm system gave audible and visual feedback with the help of a piezzo buzzer and a red LED. A connected Android device enhanced the alarm system by providing the possibility of taking a picture of a possible intruder. You learned how to programmatically to use the camera API to instruct the camera to take pictures. By saving the alarm event to a log file you also learned about one of the ways to persist data in Android.
You will find :
– Arduino sketch
– Android code
– Documentation including : List of electronic components, Circuit diagram , Arduino sketch, Android main class script, and a photo of the result.
You can enhance the code or create new one 🙂
As usual all code is documented.
