My problem is to make it start when I want.

Finally I solved part of the puzzle.

// Example code for Centipede Library

// Works with Centipede Shield or MCP23017 on Arduino I2C port

#include <Wire.h>

#include <Centipede.h>

I think something is missing, the i2c not specified, still confused?

My problem is the Centipede shield, I am not sure what type of code to use.

You might find your code is a lot tidier and easier to manage if you use some arrays.
