  1. You should never print within an interrupt routine (or do anything that takes a significant amount of time, unless you absolutely cannot avoid it).

  2. Printing takes time, so in the first program while you are printing, you are probably missing encoder state changes.

Here is a very simple program that doesn’t skip encoder state changes (for the Pololu Orangutan) Quadrature encoder for the O
