I need some one to guide me with the PR14 error
I'm already finish with the soldering and programming using the ICSP. The problem is when I turn the PR14 ON and after 15 sec from pressing the SW1, it didn't go into scanning mode but it just become so noisy.
Is something wrong with the PIR sensor? Because I did a mistake once by connecting the Vcc from the PR14 to the Ground at the PIR sensor, same goes with the Ground from the PR14 to the Vcc at the PIR. Does wrong polarity of the sensor causes the sensor to become malfunction? I change the connection back to the correct polarity, and it still make the same noises. I already turn the Delay Time with a clockwise at the PIR sensor so it can calibrated with the environment. It is not working at all.
So basically, my PR14 only make alarm noises after 15sec. Do I need to buy a new PIR sensor?
Sorry, I'm still new with this electronics stuff and trying to learn from mistakes.
I really need help on this.
Thanks
