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

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.
