This is probably a beyond noob question but I'm working on a project that uses flex sensors that require 5 volts and I want to use them with a teensy 3.2 If I'm reading correctly, the teensy analog inputs only tolerate 3.2 volts. I can obviously power the sensors from my breadboard power supply but what do I do with the control voltage? (I've already got a 10K resistor in line, but when I tried to send a signal to the Teensy post-resistor I got bogus results (and maybe fried my teensy?)
