the process

I removed these pins to avoid them being seen

here you can jumper soldered into back side, I set it for Re-Trig to send a continus signal when detecting motion

here it is from front after soldering jumper on back

installed on BottomChestV1

oscope of pin12

make sure you are not trying to trace any analog pins or you will get dashes not nice lines like these

 "trap - don't have analog traces running" 


line low at no movement,

line goes high and stays up with movement, 4 seconds after movement ends line goes low.
