How Thermocouples Work

mrpete222 on YouTube has another great video in his WHAT MAKES IT WORK? series, this time on thermocouples!  Check out the video for a great explanation of how a thermocouple built from a few pieces of metal can output very accurate temperature measurements.  You can even see how to build a simple thermalcouple with a few strands of wires.  Be sure to see the Adafruit learning system guide on thermocouples for more information on them too!
