For this I plan on using a TL072 to follow the voltage.
I just want to be clear on how I'll connect - the TL072 + input is the same + from the thermistor (before the resistors ?), and then I input this to an analog input on the arduino (or do I also need to get the output of TL072 to the resistor first to get the same result as both controllers?)
I plan on doing some tests, but would like to be sure...
Does having a thermistor on all the time use a lot of current? Will the result of a thermistor be different if you only power it for a few microseconds before reading, when needed instead?
