Hey guys below is the code for some air blast tanks.

They are not triggering the program. I have a blinking status light but that's it.

Is there something wrong with the code that the PIR isnt being triggered or is it a wire issue?

thanks guys! I seem to have 5V on both the Red and Black and Red and White, While the Black and White have 0V with no movement and around 3v with movement.

Thanks guys. (Thinking its a program issue)

The problem is you're looking for a 500ms input from the PIR when the trigger value can only go to 255 (because it's a byte). Change the PIR threshold value to 100 and it will be fine. 500ms is a really long time -- 100ms is perfectly valid for a PIR. Even if the PIR comes on half way through a 100ms debounce cycle, it will get detected at the end of the next.

Hint: Change your Font Face to Courier to make inline listings easier to read. Blue color (as you did) helps, too.

Im changing where it is Red correct?

Sorry I though I had made that all blue. Anyways I changed the 500 to 100 and that seems to have fixed the Trigger however when I read the voltage on Pin1 and 12V+ I dont see it go to 12V and the Status and Hold LEDs dont come on either. The switch is in position 2 as well. Any Ideas?

JackMan

Not sure why you are checking voltage at PIN1. In your program, the 2 LED's you are referring to are on OUT4 and OUT5.

Quotewhen I read the voltage on Pin1 and 12V+ I dont see it go to 12V

Connect the red lead of your meter to V+ and the black lead to the OUTx (not PINx) terminal you want to monitor. When the output is on, you should see your V+ voltage.

I was doing that. I had changed the code making sure it wasn't a output issue. on 12V and GND i see 12V, However on Out1 I was only seeing like 3 volts. I brought the controller back home from the haunt with me to do more debug. I'll try changing the chip and see if that fixes the issue.

JonnyMac

You may want a load on the output before measuring. Some meters don't work well without a proper load.

So you are saying that when OUT1 is LOW, the voltage is zero, when OUT1 is HIGH, the voltage is 3? Are you checking by placing the probes on the terminal block screws? If the screw isn't all the way in tight, you won't get a proper reading. When any of the OUTx terminals are LOW, you should get a reading of around 0.03v, when they are HIGH, you should get V+ voltage.
