Ever wanted to read the temperature with your arduino? Heres a great way how using only 4 wires! With the TC74!!
The temperature is accurate to about ±2°C

The things you need are:
- An Arduino (Im using Duemilanove)
- The TC47 (3.3V or 5V)
- Four(4) bits of wire
- A breadboard (Optional but helps a lot!)

Just a heads up use refer to TC74 as TC47 which may be confusing to readers. Otherwise great detailed guide!
