I followed exactly what this person did in the video so I didn’t know what I’m doing wrong thanks for any help
Also I don’t want to use a resistor because i didn’t have one but I do have a mosfet if that helps
In the video the output is driving an LED directly, meaning that the output voltage is about 1.2 volts, and probably the current is less than 20 milliamps. BUT what is shown is a PIR sysetm, not just the sensor. This system would need an external device to control anything at all. What would work easily is to use an external NPN transister that will not load the output. An MPSA13 device is one that I have used and it works very well. The emitter would connect to the system negative, (black wire and battery minus), the base would connect to the output yellow wire, and the collector would connect to the negative terminal of the small motor. The positive terminal of the motor would connect to the system positive (red wire). That should work.. I just got a pir and I am trying to make it turn on a dc motor when it detects motion I am using a breadboard a 9v battery and no mosfets of resistors, I’ve watched many tutorials but nothing seems to be working

And why exactly was that version not workingHi misterbill2 you are the most help I have gotten I don’t exactly know what u mean or where I would put it could you give a more detailed explanation I am only a beginner in this type of stuff
What I want to do is detect when a CD gets ejected from a PS4 and the activate the dc motor of that helps

If you duplicated the circuit in the video and had it lighting an LED device then it should be working. If you had a motor connected instead of an LED then it would not work because any motor requires much more current than an LED, and the PIR module is not able to deliver that much current. Also, it may be that if you used a similar white block to do your experiment there was a poor connection to the PIR module and no power to either it or the motor.Thanks for telling me what I wold need ( I will wait for your circuit recomendation) but I also have another question do you know why the circuit in the video was not working you have been a great help
