Room Management System – A circuit board design and things I am currently working on

The final stage is the creation of a circuit board. Well, I am not going through the whole process of showing how to design a circuit board. You may have noticed that I am using “Fritzing” for most of my electronic layouts and circuit designs. Fritzing is also available for free and is very well documented.

The circuit board I have designed is with the Atmega chip on board and the 5 Volt power supply option which saves us from playing around with warming up voltage regulators.

Here also the little advise, if you try to copy the design from the image, it is a double sided board and some tracks are hidden in this view.

However, if you don't feel like designing your own circuit board, just post me a message and I will send you the production files for the board.

A small preview on things I am working on next

A conversion of the Room Management System to make it more suitable for home owners:

1. Updating the code for the priority switches to stop them from changing state while somebody keep it pressed for a while.
2. How to take the Atmega chip of the Arduino board
3. Implementing a real time clock
   a) giving the possibility to set times and temperatures for more AC – control
   b) giving the possibility to add a holiday switch, switching on and off lights in a preprogrammed sequence and time while nobody is at home, giving the impression somebody is at home
   c) giving the possibility to control outside lights, switching on with photocell and off with a preprogrammed time.
4. Adding the possibility to adjust at least groups of timers without changing the microprocessor program.
5. Adding the possibility to adjust the sensitivity without changing the program in the microprocessor.
