I'm was going to be using the DS18B20. It's got 3 legs on it 1 of which is a ground that goes to the Arduino's ground plane. I though maybe I could share that ground too but by Chris' schematic the fan grounds all go through either a 10K resistor or through a 2N3904 transistor and I wasn't sure if that would work...
Which actually brought me to another question about that 10K resistor. All I have here is a huge 3W10K resistor, will that still work in that fan circuit?
