servo motor controlled animatron

This is a subset of materials available for a 14 hour year 9 course, where students use a servo motor controlled initially by a 555 timer, to mechanise an animatron (PIC based control is designed as a follow on). Course is designed to teach concepts of 555 timing leading onto pulse width modulation as a higher level concept. Circut wizard files are provided for circuits and PCB's (file extension needs changing from .txt to .cwz)
