Random functions in Arduino

In this Project, we will see about how to use Random Functions in Arduino to control LEDs .

Circuit Diagram:

Arduino Code:

random_simple_code.ino

//This Code is Developed by Sdev

void setup() {
  Serial.begin(9600);
}

void loop() {
  int rand_num = random(100);
  Serial.println(rand_num);
  delay(500);
}

random_led_code.ino

//This Code is Developed by Sdev

#define led_r 4
#define led_g 5
#define led_b 6
#define led_y 7

void setup() {
  Serial.begin(9600);
  pinMode(led_r, OUTPUT);
  pinMode(led_g, OUTPUT);
  pinMode(led_b, OUTPUT);
  pinMode(led_y, OUTPUT);
}

void loop() {
  int rand_num = random(20, 24);
  Serial.println(rand_num);
  if (rand_num == 20) {           //RED
    digitalWrite(led_r, HIGH);
    digitalWrite(led_g, LOW);
    digitalWrite(led_b, LOW);
    digitalWrite(led_y, LOW);
  }
  if (rand_num == 21) {           //GREEN
    digitalWrite(led_r, LOW);
    digitalWrite(led_g, HIGH);
    digitalWrite(led_b, LOW);
    digitalWrite(led_y, LOW);
  }
  if (rand_num == 22) {           //BLUE
    digitalWrite(led_r, LOW);
    digitalWrite(led_g, LOW);
    digitalWrite(led_b, HIGH);
    digitalWrite(led_y, LOW);
  }
  if (rand_num == 23) {           //GREEN
    digitalWrite(led_r, LOW);
    digitalWrite(led_g, LOW);
    digitalWrite(led_b, LOW);
    digitalWrite(led_y, HIGH);
  }
  delay(2000);
}
