 		 #167114 - Yes I know
Responding to: ???'s previous message
Yes, I know that when the sensor is a able to detect a moving object, it will turn off the LED. But then, it does not(original post: "But then it does not work"). Should I return it? I have bought it 3 months ago, but it is only yesterday that I had the time to test it.

I have previously connect the PIR sensor to the External Interrupt Pin to turn on/off a light connected to pin p1.7 AND WHAT IT DOES IS IT MADE THE LIGHT BLINK ALL THE TIME(Added this sentence).
