[time-nuts] Arduino Frequency Accuracy

Just in case you want to build a clock with an Arduino.. http://jorisvr.nl/arduino_frequency.html ADEV measurements, etc. take home message.. absolute accuracy is a few kHz out of 16 MHz... probably a 100 ppm crystal. On some Arduinos (or Teensy3's which is what I use) there's a provision
