I'm a newbie at this, but I just read yesterday on a web page that
servos want a signal (20 ms = ?? degrees) every 50 milliseconds or so,
and if you stop sending the signal, they "go limp" and don't "hold"
position tightly, but are deenergized and can easily turn or be turned.
I'll be testing this tomorrow and Saturday with Handyboard and an RC
servo, so I'll report back what happens.

        I have been programming lately using the recently released dual servo
routines.  I have noticed that if I enable both servos and simply send each of
them a pulse (servo_a7(or 5)_pulse=3040 for example) they respond faitfully but
then twitch almost imperceptibley every few seconds.
