Randomizing!

I was able to figure out how to randomize the mux! Here is a video:

And the code:

int pwrArray[4] = {4,3,2};

int gndArray[4] = {5,6,7};

int pwrRandom;

int gndRandom;

void setup () {

  

  for(int ii = 0; ii < 3; ii++) {

    pinMode(pwrArray[ii], OUTPUT);

    pinMode(gndArray[ii], OUTPUT);

  }

  Serial.begin(9600);

  randomSeed (0);

}

void loop () {

  

  pwrRandom = random (0,3);

  gndRandom = random (0,3);

  

  digitalWrite(pwrArray[pwrRandom], HIGH);

  digitalWrite(gndArray[gndRandom], HIGH);

  

  Serial.print (pwrRandom);

  Serial.println(gndRandom);

  

  delay (100);

  

  digitalWrite(pwrArray[pwrRandom], LOW);

  digitalWrite(gndArray[gndRandom], LOW);

}
