It's been ages since I posted, and I've been taking my first serious look at using analog sensors with an Arduino. I thought thermistors would be easy enough....

Better Thermistor Reading with an Arduino: Series Resistors & Aref

And they are...sort of...until you start trying to power them from a digital pin (which was a mistake) or speeding up the ADC, or simply using cheap eBay crap like I usually do...

Anyway, I'm finally getting the hang of it, and if I can weave enough tests into the schedule to sort out the last few details, I promise the next post will be interesting...
