I am starting out new here with Robotics and trying to make a puppet head movement using servos and switches. I have the basic design and movement but wanting to move furthur. I am using digital servos for the up and down and side movement with a sparkfun servo trigger but i can only get a center to left or center to right movement, not both. Is there a simple way to control the servo to go from center to left back to center then right and back with a simple switch control. Its for a shoulder puppet that she wants to control with just with a few swtches she could hide in a puch os fanny pack or something like that?
Servo Trigger
Three Control Settings:
- A - sets the position the servo sits in while the switch is open
- B - sets the position the servo moves to when the switch is closed
- C - sets the time it takes to get from A to B and back
If you only get centered to -90 degrees, then it’s a settign above. If you get centered to -180 degrees, then the head is placed at the wrong angle on the servo horn. If you want more complex motion, you’ll need a servo recorder / playback, or program a servo controller / microcontroller.

Servo Triggers
I guess being new at this I am trying to go real simple and real small on these creations of hers. Lets go at this angle. I want to connect a servo to the head of her puppet and make it start at the center point which would be looking straight ahead then look down with the push of a button or switch, then back to center then with the push of a button or switch it would look up an then back to looking straight ahead. Am I making any sense on what I am trying to accomplish? I believe the servos I am using might not be able to accomplish this feat. They are some Tower MG90S that I had laying around and I was using a Servo Trigger on them.
Any other suggestions wouls be greatly appreciated!
