digital write pin issue
-
Hello all,
I'm want to use a pm25 kit to control my HVAC.
Everything works fine untill i add a digital write pin.
Sensors stop reading.
What is wrong. I also put in some logic but deleted it to keep it simple. What is wrong with the digital pin? I put the digital pin in another program with a wait in it and cycle from 0 to 1 it just works fine.

Now i have to built a relay cirquit for our 230volt net.Thanks!
