About randomSeed(analogRead(0))

[system]

.....the function call random() runs an algorithm that creates a pseudo-random value based on a seed.

Since reading analogRead(0) would be an effectively random value, this effectively, gives you a random seed.

Thank you for the reply.

what do you mean pseudo-random?
why you state that analogRead(0) would be an effectively random value? How to know that?
