I am having trouble getting my Handyboard to interpret the readings correctly from a temperature sensor. I'm not sure if the schematic online is correct and could use any help whatsoever. The sensors I have are the lm335z and the lm35, which should i use and how should i go about connecting it to the analog input of my microcontroller?
