    Anybody here knows how to convert from sine waves to pulses?

    Schmitt trigger?

    Comparator?
     
  3. A schmitt trigger is a comparator with positive feedback, to give it
    snap action hysterisis. It is good at turning any slowly changing
    wave into a two state (digital) output. You can buy logic gates that
    include an internal schmitt trigger, but if you want to adjust the
    exact voltages that it changes state with, you should build one with a
    comparator.

    don't forget "clamping" the voltage with diodes after the series resistor
    if the sine voltage is too high.
