They're one wire temp sensors so they present the temperature digitally with a unique identifier, similar to a MAC address for computer networking. You can run I think up to 8 in parallel.Random question
If you're wiring both the temp probes together how the hell does the board distinguish the two sets of info?
The screen needs 5V. Ensure the power for the screen is coming from the AC-DC convertor and not the 3.3v on the wemos.Have the board flashed and I think everything's ready for my sparky mate to check it.
Few questions about it only being on USB power;
- Should the screen work? atm all I've got it a backlight on, no data.
If i understand you correctly, yes you can. While it is running you can add an angle and gravity and it will update it no problems
