I need help setting up Raspberry Pi Model B to control Car Door Lock unit(s).
I have connected my Rpi to a relay which looks like this :
I wish to clarify what is NO, C, NC and how do they operate...
Here is the image of the door lock unit.
The 12V DC supply is needed for 1 second to lock and reverse connection for 1 second to unlock.
How to configure the pi to turnoff the relay in 1 second?
Should i connect the power supply out fom NC or NO?
Because when the relay power goes off, the lock should not open...
Any help would be deeply appreciated.
