@hard-shovel It worked! I used pin 4 on the D1 Mini and did direct power and i'm reading temps now! Thank you so much! One final question about the pinouts. Is there some kind of guide that you know of to determine which pins to use? i.e. how did you know how to use pin 4 on the D1 Mini but keep 2 specified in the sketch? Please ELI5.
@zboblamont Moved yellow jumper from 21 to 25 as suggested and I'm still getting -127.00 on each line. Any other ideas?
@hard-shovel you are definitely not stating the obvious. As originally stated, I'm a complete noob at this stuff and I'm not aware of what all these acronyms mean yet haha I'll definitely have to remember that in the future when looking up pinouts and the like. I will let you know how this goes! Thanks again for all your help!
