@elmerito25 Hi:
Thanks for the reply. The PIR has two rheostats labeled Sx and Tx, so which is which. I’m tempted to dispense with the PIR altogether and just use the monitor on/off switch to activate the display. But, I’ll mess with the PIR when I get a chance and see if I can get anywhere. Using Board numbering, the PIR has its VCC pin wired to pin 4, its ground pin wired to Pin 6 and its signal pin wired to Pin 7. I set the pin number in my config.js file to 4 (Board pin 7 is GPIO pin 4). Would there be any problem with this wiring?
