I bought my home in early September 2012. I noticed that flies were flocking around a light in my open air carport whether it was on or off. I tried a few products like fly tape, spray and a fly trap. Still no results. This continued through fall until temps dropped. This Spring I thought I would take preventive measures and cleaned my entire carport with Lysol including my garbage cans which are new. But still flies are flocking around this light. Its strange, they don't land on it that much as if there were some food source. They just fly around it all day until the sun goes down and even then there are a few stragglers. I would say at peak during the day there are about 150 to 200 flies. Why are they attracted to this area and What do I do to get rid of them? 


Question: How do i measure the output voltage of lm35 with digital voltmeter?
Answer: Yes you definitely can because the analog pin is set by the IC with respect to ground.

You probably know this but if you are going to use a voltmeter, don't touch the leads of the LM35 with the voltmeter probes directly, because if you short it, you will experience the all too familiar smell of burning electronics.
