![]() ![]() Set a random number in randomSeed() when running the program.How to generate random numbers so that the sequence is new every time? There are options: Value is any number of unsigned long types, so we have 2^32 (4,294,967,295) sets of pseudorandom numbers on the Arduino. ![]() randomSeed(value) – give the pseudorandom number generator a new reference point for the count.random(min, max) – returns a pseudorandom number in the range from min to (max – 1).max takes unsigned long, that is, from 0 to 4,294,967,295. random(max) – returns a pseudorandom number between 0 and (max – 1).The Arduino has a couple of ready-made functions to work with pseudorandom numbers. In this article, let’s figure out how to correctly set a random number in a range in the Arduino IDE. The randomSeed function allows you to place a variable or constant into the random function to generate more random values. The Arduino random function returns a pseudorandom number, which means that the random number generation sequence is still predictable. ![]()
