I am a beginner and have very little guidance to support my work,so pardon me for some foolish questions or been ignorant to certain facts,it's only during my final year project of engineering I have found liking to uC and electronic work,so please do guide me.It will take me a few years of reading and understanding to get hold of things and solve my problems
I hope you people can share a few valuable moments to help me.I am also trying to share the knowledged gained from my experience on my site .

Coming to the work I have in hand, the following clarification in form of a flash animation is here.

Due to long distance aprrox 1m from board I feel using +12V or 24V supply is better than +5V supply for reed relay and Pressure Switch contacts (I hope my wiring is right)
