hello,
I tried run MAX31855 with Arduino UNO using Adafruit product/269,
But, temperature readout decreases when I put my hands on the type - k thermocouple tip.
it is supposed to increase. I reversed the polarity of the two thermocouple wires, the readout becomes to increase as expected,
I am wondering what is wrong, or it is just the wrong label on the board for thermocople wires (yellow and red).

Re: max31855 with Arduino
Sounds like the color coding on your thermocouple is the reverse of normal. We see these occasionally.
