I just read from Input Impedance of A0-A5 that
whatever you connect to the A/D have an output impedance of 10k or less for best accuracy
However in Using a Thermistor they're using a 10k resistance + a 10k (25°C) thermistor connected in series.
Thus the resulting resistance should be roughly between 42k (0°C) and 11k (100°C).
Both Ω being way above 10k.
Wouldn't it be better to not add the 10k resistance (so the range would only be between 32k and 1k)?
Please enlighten me
