  • Managed to get the TMP102 work with the Arduino Duemilanove even though I do not have any Logic Level Converter. Apparently, the 3.3V part does not go up in flames when exposed to 5V on the SDA and SCL pins though I can not know if there is any internal damage.


  • Fritzing starter kit has arrived. Good value for money.
  • Recreated the temperature sensor mockup using the breadboard, see Ustream recording.
  • Often the readback from the TMP102 returns error – could that be due to the volt mismatch? I will put wirk with TMP102 on hold until I get a Logic Level Converter.




  • The Logic Level Converter has arrived. Reworked TMP102 connection on the breadboard.
  • Followed the instructions [ here] except that I connected V+ of TMP102 to 3.3V instead of 5V. Also tried to connect to 5V and that worked too, but then again, it also worked without the level converter
