i power all my stuff external.
NooM, forgive my ignorance, but does that mean you have one PS which powers the Netduino, and another which powers your sensors? Does that mean you have two connections to Mains, or are are you using two sets of batteries?
Regarding the capacitor: Is it simply a matter of putting the capacitor between +3.3 and the Power Input of the TMP36? Is that simply to smooth out the voltage, in-case of minor dips?
Thanks so much!
