Is it a variable resistor value ?
Is there a way to know precisely the resistor value ?
I am thinking using the internal pull-up resistor so i can connect directly the thermistor to the pin and the ground.So i don't need to connect a lot of 10k resistor, one for each thermistor.
I was able to calculate the internal pullup resistor and the value is 34kOhm for my Arduino Uno board but what is wrong to use the internal resistor ?
