Random Behaviour

Im working on code that will make blobs behaviour unpredictable. So that every time it gets bitten it reacts differently. The code isn't finished yet but anyway.

ARDUINO CODE

// set pin numbers:
const int buttonPin = 7; // the number of the reedswitch pin
long randNumber;
//const int motorPin = 8; // the number oh the motor pin
// variables will change:
int buttonState = 0; // variable for reading the pushbutton status
int pin2 = 2;
int pin3 = 3;
int pin4 = 4;
int pin5 = 5;

int timer = 100;


void setup() {

// initialize the reedswitch pin as an input:
pinMode(buttonPin, INPUT);

// initialize the motor as as output
// pinMode(motorPin, OUTPUT);

// initialize the LED pin as an output:
pinMode(pin2, OUTPUT);
pinMode(pin3, OUTPUT);
pinMode(pin4, OUTPUT);
pinMode(pin5, OUTPUT);
randomSeed(analogRead(0));
Serial.begin(9600);
}

void loop(){
// read the state of the reedswitch value:
buttonState = digitalRead(buttonPin);

// check if the reedswitch is pressed.
// if it is, the buttonState is HIGH:
if (buttonState == HIGH) {



// turn LED on:
randNumber = random(5);
delay(50);
Serial.println(randNumber); }


if ( randNumber==1){
digitalWrite(pin2,HIGH);
delay(1000);
digitalWrite(pin4,HIGH);
delay(1000);}

else if ( randNumber==4){

digitalWrite(pin2, HIGH);
delay(timer);
digitalWrite(pin2, LOW);
delay(timer);

digitalWrite(pin4, HIGH);
delay(timer);
digitalWrite(pin4, LOW);
delay(timer);

digitalWrite(pin3, HIGH);
delay(timer);
digitalWrite(pin3, LOW);
delay(timer);

digitalWrite(pin5, HIGH);
delay(timer);
digitalWrite(pin5, LOW);
delay(timer);

digitalWrite(pin5, HIGH);
delay(timer);
digitalWrite(pin5, LOW);
delay(timer);


digitalWrite(pin2, HIGH);
delay(timer);
digitalWrite(pin2, LOW);
delay(timer);

digitalWrite(pin4, HIGH);
delay(timer);
digitalWrite(pin4, LOW);
delay(timer);

digitalWrite(pin3, HIGH);
delay(timer);
digitalWrite(pin3, LOW);
delay(timer);

digitalWrite(pin5, HIGH);
delay(timer);
digitalWrite(pin5, LOW);
delay(timer);


digitalWrite(pin5, HIGH);
delay(timer);
digitalWrite(pin5, LOW);
delay(timer);

digitalWrite(pin3, HIGH);
delay(timer);
digitalWrite(pin3, LOW);
delay(timer);

digitalWrite(pin4, HIGH);
delay(timer);
digitalWrite(pin4, LOW);
delay(timer);}



else if ( randNumber==2){
// i=0;
// turn LED off:
digitalWrite(pin2, HIGH);
digitalWrite(pin4, HIGH);
digitalWrite(pin3, HIGH);
digitalWrite(pin5, HIGH);}



else {
// turn motor off:
//digitalWrite(motorPin, LOW);

// turn LED off:
digitalWrite(pin2, LOW);
digitalWrite(pin4, LOW);
digitalWrite(pin3, LOW);
digitalWrite(pin5, LOW);
