Servo Software

So, given that I've been playing with servos it seems that producing something simple to drive them would be a good idea.  If you are of a mind, and fancy  a modest challenge, then over HERE (in Github) is the source for the Arduino firmware.  This, after relatively limited testing, should work on a Nano, Uno or Mega2560 and control as many servos and the board has PWM outputs (with some reasonable exceptions).   Here (and arguably meaninglessly) is a picture of an Uno operating a sing
