Yes perfectly works well ... (I think i was giving resistor when grounding while in this case, it is to +ve) Thanks a lot but i will be in more better way for my further proceeding if you can let me understand why this just 2 cap addition worked fine ? or just logic behing this so that i can proceed to work with http://www.instructables.com/id/Perfboard-Hackduino-Arduino-compatible-circuit/?ALLSTEPS where i think that i will attach PIR motion sensor to get activate my door bell or passage light with LDR + PIR + Relay with perf board version to get more in-depth understanding for my first project on my own, without arduino board. and what other precautions should be taken care in that type of work.
Thanks to tom, jimboza, Zapro, fungus for answering my quety... i feel much better now and you may help me in further understanding and extending knowledge in future too please.
