I have a new library submitted for public use, It's called Tinker-Servo and contains the normal tinker library calls plus four new ones:
You are allowed up to eight servos open at any one time.
/servoOpen - Takes a gpio pin i.e. D1. Returns a index to the server used. This index will be passed to the remaining functions to perform operation on the servo.
/servoClose - Takes a servo index returned by servoOpen. Calls servo.detach() for the pin assigned.
/servoSet - Takes a servo index and a angle (0-179).
/servoRead - Takes a servo index and returns the last value sent to the servo.
I am working on a browser based servo tester/driver now and will have it in the github project once completed.
