Ultrasonic sensor/PIR

Will the LCD extension cable work for the ultrasonic and PIR parallax sells, or do I need to go looking for a servo extension cable?


About the PIR, how do you hook it up, 5vdc, GND and the last pin the the microcontroller, but on this wire, should i have a pull down resistor or something, my PIR is not working.


Thank you

    How are you testing the PIR? You should be able to see a change in the output pin with a meter, no need for a micro or a progrqam.

    Is the LED flashing?

    Is it a ping or generic?
    The generic I have has the input and signal pins reversed from the regular stamp servo wire setup. It puts out a simple hi low output.

    Yes, the same cable works for both. I hope this helps. Take care.
