My peltier wine cooler doesn't function as it should. I think it's the power/logic board the maintains cold temperatures shorted. So I was thinking of replacing it with an external power supply and an arduino as the controller.
I have a question about the temperature sensor that's attached to the Peltier device.
It's in the block below the peltier. I have no idea what make/model it is since it's inside the metal block. The temperature sensor changes in ohms depending on the temperature. How can I use input into the arduino? Send 5v through it and into the arduino analog input? I'll then have to figure out the temperature formula base on the voltage I get?
I could easily use a more arduino friendly temperature sensor if this is too much of a challenge.
