Lab 1: Blinking LED

Description:
Create a simple circuit that will make a LED light blink in intervals that are based off of code programmed into an Arduino.

Items used:
- 1 Arduino Uno
- 1 Breadboard
- 1 220 ohm resistor
- 3 connector wires
- 1 Green LED
 
Code:

// 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(600);               // wait for a second

  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW

  delay(300);               // wait for a second
 

}
