DS18B20 connection

[mnfisher]

Here's a simple example...

I used a DS18B20 with data on pin 8 and used pin 9 as Vcc and Pin 10 as Gnd.
You'll also need a 4k7 resistor from Vcc (or pin9 - not the easiest wiring choice) to pin8.
Should also work in parasitic mode.

I used an Uno - but should work as is on Nano (just change target...)
