This code just prints out the current temperature sensed by a TMP102 temperature sensor over serial when requested. Here's the Python code that lets you log data locally and to a Google Docs spreadsheet: https://github.com/m01/Tiny-Temperature-Logger For an example, see: http://playground.m01.eu/live-temperature For general information about the TMP102 and mbed, see http://mbed.org/cookbook/TMP102-Temperature-Sensor An additional wiring diagram can be obtained from here: http://wiring.org.co/learning/libraries/tmp102sparkfun.html
