Can any one guide me to a post or suggest a course of action. I am new to arduino and wish to learn quick.
My 'system' would have multiple magnet switches (like on a window or door). I wish each magnet switch to be a separate entity in that if it is broken the adruino will acknowledge magnet #1, 2 or 3, etc was opened(or multiple openings). The open magnet would set off an alarm.
I wish to be able to have a programmable delay that would allow me to set the time between open magnet and alarm sounding.
Once the magnet is placed back in contact the alarm is turned off. I wish to have a display that tells me my set 'time delay', what magnet(s) was opened.
Any ideas, suggestions, guidance.
Thanks much gang. If you need any clarification feel free to critique.
I believe its even possible to chain several sensons on a bus-line and be able to detect which are open/closed.
This can be obtained by adding unequal valued resistors and 1 analog input.

Reed switch is nifty and small. Me likey. I saw some larger always on/off magnet set ups but this might make it more 'micro'.
Does anyone have a schematic of how I could make this device?? with all its bells and whistles. It's seems simple. Is there a tutorial that might move me along without having to learn C-language, etc.??
