Time to build a temperature sensor with my Pi.
Schematics
Configure the Pi
Update the OS
This not necessary, but generally a good idea.
apt-get update apt-get ugrade
Setup kernel modules for GPIO and 1-wire device
modprobe w1+gpio modprobe w1+therm
Check setup
Check whether there is now our sensor device:
cd /sys/bus/w1/devices ls

cd XX cat XX
Result:
?
