Description

Make 3 LED lights blink at the same time with high/low less than 1 second. 

 

Components Used

1- Arduino Uno

1- Breadboard

1- 220 Ω Resistor

1- Green LED

1- Blue LED

1- Red LED

 

/*
  Blink
  Turns on an LED on for .05 second, then off for .05 second, repeatedly.
 
  This example code is in the public domain.
 */
 
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;

// the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);     
}

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(50);               // wait for a .05 second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(50);               // wait for a .05 second
}
