-randomSeed(seed)
-================
-
-Description
------------
-
-randomSeed() initializes the pseudo-random number generator,
-causing it to start at an arbitrary point in its random sequence.
-This sequence, while very long, and random, is always the same.
-
-
-
-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.
-
-
-
-Conversely, it can occasionally be useful to use pseudo-random
-sequences that repeat exactly. This can be accomplished by calling
-randomSeed() with a fixed number, before starting the random
-sequence.
-
-
-
-Parameters
-----------
-
-long, int - pass a number to generate the seed.
-
-
-
-Returns
--------
-
-no returns
-
-
-
-Example
--------
-
-::
-
- long randNumber;
-
- void setup(){
- Serial.begin(9600);
- randomSeed(analogRead(0));
- }
-
- void loop(){
- randNumber = random(300);
- Serial.println(randNumber);
-
- delay(50);
- }
