Control System Principle

SMART HOME SYSTEM (ANDROID PROGRAM)

This is the program source code for my application which can control arduino's bluetooth module. It was the java code for this SYSTEM that I have build for myself. It still be okay for your source in making the application like that. This classes code just for communication within bluetooth modules.

The Code :

Tips to Expert in Programming:

1. Remember that ANY programming language is like an essay that should be read from the beginning to expert and go through its own flow based on its given instruction!!!

2. Be sure you know what every code syntax does means!!!

This circuit diagram is an example of inverter of a CMOS before IC layout presention we would use.
