Title: Adding External temp code for TMP36

This is what I've come up with so far to measure the external temperature. I'm using a TMP36 from Adafruit.

There's a few things I could try from here: compare this sensor to another temp.sensor(DS18B20), improve precision by changing reference voltage, improve stability by applying a filter, apply weather-proofing, log data onto an SD card or a website, explore using it in feedback control...
