So I solved the issue of not having a sensor, went to a security store and got a low voltage motion sensor. I wired it up to what in thought would be right, but when I connect it to the pico the programed cycle just goes and goes and doesn't stop.
I did a little reading and searching before posting, but I'm wondering if anyone has any suggestions to hone me in on what to fix
Thanks for your time

Sounds like the expected trigger signal is wired wrong. Your motion sensor trigger is either “Normally Closed” (NC) or “Normally Open” (NO). Could be either and programmable. Then the motion sensor itself has power and ground which if a home security sensor would be 12VDC.

(NO) means the trigger is open until motion is detected. Then +12VDC will momentarily be applied to the trigger while motion is active.

(NC) means +12VDC will be active on the trigger at all times until motion is detected. Then the trigger will momentarily go open while motion is active.

On the motion detector - This is assuming you are using a positive trigger. Substitute GROUND in-place of +12vdc for a negative trigger setting.

Your trigger setup needs to match your pico expected trigger.

Sounds to me like you have NO/NC swapped or trigger polarity is wrong….

There are instructions included on how to change the pico from NO to NC trigger.

Thanks guys
I am going to give it another shot tomorrow. I thought i wired it like the one I got from Fright ideas, but I guess they could have swapped the jumpers before sending it to me...

I think you are close. Must be the NO/NC.
