Hi
I intend to connect 3x DS18B20 sensors to my UNI.
Do I need to include a pullup (4.7k) resistor from the DATA to VCC line as I would with pi/ESP32 etc?
For powering the UNI I have a 24V PSU, but don't understand..
Do I only connect +ve to pin 1, and ground to pin 2?
What about -ve from PSU?
(sorry, electronics n00b!)
A wiring video or photo would be very helpful.
Thanks!
