Welcome to AAC!

A thread belongs to the OP (original poster). Trying to take over someone elses thread is called hijacking, which is not allowed at All About Circuits. I have therefore given you a thread of your very own.

This was split from http://forum.allaboutcircuits.com/threads/sensors.106198/#post-812989

And sounds curiously similar in lacking detail as in the previous post on RIFD.


Do you honestly expect anyone to answer your question with the limited information that you posted?

Where is your schematic? What have you done to troubleshoot this problem? Exaclty what part of the project is giving you trouble?
