Commonly used are current time values (using millis() ), but you could also try something else like user intervention on a switch or antennae noise through an analog pin.
long, int - pass a number to generate the seed.
no returns
long randNumber; void setup(){ Serial.begin(19200); } void loop(){ randomSeed(analogRead(0)); randNumber = random(300); Serial.println(randNumber); }
