Webbrandom() randomSeed(シード) 関数randomSeed(seed)は、Arduinoの疑似乱数ジェネレーターをリセットします。random()によって返される数値の分布は本質的にランダムですが、シーケンスは予測可能です。ジェネレータをランダムな値にリセットする必要があります。 WebbAlthough Arduino generates random numbers using the random () function, the sequence of the numbers will eventually become predictable. This is because Arduino uses a “default” random seed. This seed will be used again when the program restarts so the resulting random numbers will essentially be the same.
WebbThe random() function can take two arguments 1) the minimumvalue of the number we want generated 2) the maximumvalue we want generated. //Create a random number and assign it to the randomInt variable. randomInt = random(0, 10); I will use 0 for the minimum, and 10 for the maximum.
