I need a little help getting the idea I have working.
First I bought this PIR module:
**broken link removed**
I have this working fine on a 9v battery. When I wave my hand in front of it I get 3.3v on the output line.
This is where I need help. I want that 3v output to fire a relay that can switch the 9v from the battery. If anyone could help me get this going I would be very grateful!
