+  The intention here is to make a ball of wires that someone can reach in and
+  grab, changing the behavior of the system.
+
   So we read in the free IO lines, build up a variable.
   If it has changed,
     do the change actions:
         make a bzzzzt sound
-        vibrate the motor
         turn off all of the LEDs for a brief instant
-  
+
     Use the created variable to choose the neopixel pattern
     and the sound pattern to output to the audio (intermittent beeps)
 
- 
+
   This program depends on neopixel library.
