This means that you plug its one signal into an interrupt port. I can see both the power wires going into the same two pins, but that still leaves one unaccounted for.įrom the spec, it looks like they combine the trigger signal and the echo signal (interrupt) onto a single port. The number of pins is the most confusing thing. You only need the rectifier if you are driving an inductive load (an incandescent bulb, motor, or relay). Since you are just driving LEDs, you can eliminate the rectifier in the diagram I mentioned above. You can build the circuit as shown, and just plug it into a VEX Y Cable along with the PIR module, and you should get your desired result. There are several threads around that talk about wiring up a transistor to a Vex digital output port to control small DC loads. Once you’ve got that, you may as well just do away with the relay and let the transistor control the LEDs directly. The PIR module can’t really drive relays directly, so you’ll need a transistor for that. When the PIR activates, it triggers the relay to turn on LED’s.Ī relay would probably be overkill for LEDs. Can you recommend a relay that is compatible the PIR sensor. I would like to automate the eyes to turn on automatically when someone walks by and then go off after a period of time.

… However, on one of my robots, I have LED’s for the eyes that use a manual switch to turn on/off.
