Touch Wiggle Servo example via Andrew Quitmeyer

TouchWiggleServo

/*
   This is an extension of Martin2250's ADC touch examples
   to have the library built in, for rapid deployment in workshop settings

   In this one, you can hook a servo directly up 
  and if the sensor passes a threshold, the servo will wiggle around
