Most the documentation I have found is using print for a random number generator but I can't get an idea of what to do. I need it for an array of leds. If someone has an idea of where to start let me know.
Edit1:
I'm trying to slow down a cycle of leds using randomseed(). I want to randomly choose a time in the array led cycle to slow down for 1 second. As you see I think I have the time issue sorted? Now I need to do the randomseed but I don't have a clue and anything I find to help is with numbers and print.
randomSeed (analogRead (0));
long oldperiod=period; // remember old period
period=4500000;// set new slow period
Timer1.setPeriod(period);// make it so
delay(1000); //1 sec
period=oldperiod; // put old period back
Timer1.setPeriod(period); // make it so
can I use this somehow?
randOn = random (100, 1200); // generate ON time between 0.1 and 1.2 seconds
randOff = random (200, 900); // generate OFF time between 0.2 and 0.9 seconds
digitalWrite(ledPin, HIGH); // sets the LED on
delay(randOn); // waits for a random time while ON
digitalWrite(ledPin, LOW); // sets the LED off
delay(randOff); // waits for a random time while OFF
