Rice Krispies Loader

This is the code for the Rice Krispies Loader robotic arm project

This code times the movement of 4 servos for a robotic arm. This arm moves downwards and then up again when either a button is pressed or a force resistance sensor is touched. The sequence of movement is useful because all the servos aren't activated at the same time; instead they happen in a smooth succession with the base servo leading to the arm servo, then "hand" and "finger" servo in a domino effect. This was necessary because the arm needs to dip into a bowl of cereal and for this the base had to move first and then the rest of the parts follow. The inverse sequence of parts (with the same timing) happens going back up and only after the down and up movement is complete can the arm be activated again.
