what is the "star" thing on the sidebar? is that what people in the room think is interesting, so they star it?

Hi!
 
12:44 PM
@KyranF yeah, although some people are guilty of using it as a personal memory
 
1:14 PM
@W5VO i'm disturbed that 2 of the starred things are from me
 
I could cancel the stars if you want
 
dw bro, i'm famous now
seeing stars
bring it on
i got 2K+ now, i'm unstoppable

Anyone here?
From what I see, analog output comes out of the differential pressure meter, and the Arduino has analog input pins.
 
@Undo yes, but not directly
it's a 0-5V analog signal, and the Arduino is 0-3.3V.
 
ah
 
@Undo or at least I think the arduino is 3.3V
(shows how much I use them)
 
> Input Voltage (recommended) 7-12V
What's that mean? That it can only detect between 7 and 12 volts?
 
@Undo well, that's the power supply input, not an analog input
actually, you're fine
 
3:28 PM
ah
 
I thought the Arduino was using a 3.3V supply, but it uses a 5V supply (which matches your sensor)
 
Ah, nice!
Thanks!
@W5VO Could you do me a favor and look over homeautomation.stackexchange.com/questions/116/… to see if I'm missing anything huge?
(looks like you don't have an account, the visit link on area51.stackexchange.com/proposals/55835/home-automation should let you in)
 
@Undo I think they make differential pressure sensors, which may be a better fit, but I don't have time to look right now
 
@W5VO I think that's what it is, right? Anyway, thanks for the help!
I really appreciate it
 
@Undo I totally missed the other port. Yup, that's it.
 
3:38 PM
Awesome, thanks!
