That's EXACTLY what I was looking for - gives me that specific context that ties the features of the chip to the functionality of the Netduino. I really appreciate this."The TMP35/TMP36/TMP37 are low voltage, precision centi-grade temperature sensors. They provide a voltage output that is linearly proportional to the Celsius (centigrade) temperature." This means the microcontroller has to have an analog input that can measure voltage - this feature is known as Analog to Digital Converter (ADC) and Netduino has its 10-bit ADC accessible via 8 pins labeled "Analog In 0 .. 7", you can use AnalogInput class and its Read() method to get the digital value of measured voltage on a certain pin (the value in range [0, 1023] represents voltage [0, Aref]). Hope this helps.
BTW, having looked at I2C a little more, I'd be interested in any Netduino-specific details on how I might use it (samples, etc).
Thanks.
