Hello,
I would like to ask you how to make a small motor as a rotational speed sensor for microcontroller, i.e. I want to pick up the output from the motor as from a small generator. I need to amplify voltage the motor produces (it produces from 0 to 0,7V) to match microcontroller's readings (from 0 to 5V). Shall I use common-collector or base amplifier? How to protect a microcontroller from damage?
Thank you!
