Generate PPM signal with Arduino | QuadMeUp

26/05/2016· In the beginning of this year I''ve written a short tutorial how to read PWM signals from RC radio with Arduino. While it is can be useful when building own RC equipment, it does not help much when one has to deal with PPM (CPPM) signal. Let''s be honest, PPM is much more useful than PWM: all RC channels are sent over single wire. On one side, it simplifies electrical design.
