To start the demo, presss the button once. The motors dance a little dance, which runs a bit under a minute. The dance illustrates some of the different qualities of motion which can be had from this configuration of components.
This demo shows three model airplane servos being operated from an 8-pin PIC microcontroller. An interface device, a "Mini SSC2" controller board from Scott Edwards Electronics, takes simple commands from the microcontroller and controls the position of up to eight servos. The person programming the PIC chip sends commands to the motors by simply sending (1) the number 255, then (2) the number of the servo to be commanded, then (3) the desired postion of the servo. A good programmer would write an interrupt-driven scheduler to do the job of the Mini SSC2, but some people would rather spend the extra money to write simpler code.
The source code for this demo is MiniSSC2.C
