Random Function

The random function returns a random number.

random(int max)

Returns a random number.


You need to give it an int called max as an input. This int is the biggest number you random is allowed to return to you as a result.


It returns an int between 0 and the the max input.


// creates a variable called number // sets the number variable to a random value between 0-100 int number = random(100); // prints the number to Serial Serial.println(number);


This function is useful when you want to have unpredictable results. For example you could use random(6) to simulate rolling a die.


Hi awesome backer,
