Can I use a transistor to switch fluctuating voltage?
I have a connection which I need to have switched on/off with current from another source. Can I use a transistor to allow current/voltage which fluctuates from 10mV to 3.3V, and serves as a data connection? I have struggled to find anything which is small and easily purchased that would do as I need. I am coming down to the wire in this project, so any help is greatly appreciated. -Sterling
