DIY Doggy Style Persistence of Vision!


POV or Persistence of Vision where you use flashing LED lights to display letters in motion, has always been a fun way to learn about LEDs and circuits.   You might remember I invented the world’s first Golf club POV, which was capable of showing letters/images while you swing the golf club.

This also means you can’t read the state of modifier keys like shift or control independently.
