If it is important for a sequence of values generated by random() to differ, on subsequent executions of a sketch, use randomSeed() to initialize the random number generator with a fairly random input, such as analogRead() on an unconnected pin.

The Arduino programming language Reference, organized into Functions, Variable and Constant, and Structure keywords. randomSeed() initializes the pseudo-random number generator, causing it to start at an arbitrary point in its random sequence. This
