I am building a motion sensor activated cat toy so my cat will spend a little less time annoying me. I have a PIR motion sensor. 5v-12v to power the sensor. The output however is only 3.3v. I have a 9v battery powering the sensor but the + to the motor is supposed to flow through the sensor which again is only 3.3v. That is not enough juice to make the motor go. The motor will run when I connect the battery directly. If I remove the motor and attach an LED as a tester the light does come on. So I know the problem is simply not getting enough volts to the motor. I bought a relay but I cannot figure out how to connect it properly.
Any help would be greatly appreciated. Please keep in mind I am a novice. I am not an idiot but this is my first project building a circuit.
