Syntax random(max) random(min, max) Parameters min - lower bound of the random value, inclusive (optional) max - upper bound of the random value, exclusive Returns a random number between min and max-1 (long) text/html 2024-02-16T01:04:17+02:00 https://code-reference.com/arduino/random_numbers/randomseed?rev=1708041857&do=diff 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.
