Community Question

Hey guys.

I need a little help with a small PIR sensor I picked up. Operating voltage is 4.5 v upwards so have it plugged in to D0 as analog won't be enough to power it (tried it on ADC0 but voltage meter shot up to 220). Could someone offer me a Short script example for me to work from to test if the sensor is working? I had a quick look on the forum but the very few entries I found were regarding ADC.

Many thanks.

It's all good. Nothing wrong with a bit of efficiency, lol.

@Steve... To be honest, I do like the challenge... But you my friend, don't need much if any help anymore... Both of us will be leaning from other guys now...

Lol, I wouldn't go that far. I still have some potential questions I may need to ask about a couple of other items I want to incorporate (if I can't sort it myself that is).

Can someone help me ?

Im a newbie. I want to use my HC-SR501 Mini PIR Infrared Modul.
How I connect this modul on the Digital Port ?
