Random number generation on the ESP8266
Soooo random! For an ESP8266 project that sends randomised tweets, I need to use a random number generator. In such a deterministic system such as a digital computer however, true randomness is hard (impossible) to come by, so we must settle for a pseudo-random number - that is a number that is part of a seemingly random sequence and is generated algorithmically from the previous number(s) in the sequence. It is good enough for our purposes. The simplest implementation of a pseudo-random number generator (PRNG) is a Linear Congruential Generator , i.e. X n+1 = (aX n + c) mod m
