// controls one servo (you can have a maximum of 12):

The guts of my Mummy

This was an exciting project.  I used one flex sensor, one motor and a servo.  The action is activated by "hurting the mummy" - this means bending him in places he does not want to bend.  This upsets the Mummy and as you hurt him, he begins to writhe in pain - flailing his arms as his head spins.
