Newbie in need of a little help (DS18B20)

I did not mention that as it adds to code complexity and you still need a free pin to feed your sensors.

What do you mean a free pin? For parasite mode power comes on data pin.

and you still need a free pin to feed your sensors.

Yeah, you are right, what was I thinking when I made that post?
No idea...

Actually, there is a recommended parasitic configuration that uses two output pins from your CPU, one to drive a MOSFET to provide a better power supply for the single data/power wire. See Figure 6 in https://datasheets.maximintegrated.com/ ... S18B20.pdf
