LED Blink

Solving Approach

How do you plan to solve it?

•  Arduino
• LED
• Resistor (320 ohm) 

1. Connect the positive leg of LED to one end of the resistor.
2. Connect the other end of the resistor to pin 7 of Arduino.
3. Connect the negative leg of LED to GND on Arduino.
    

Code

#define PIN = 7;

void setup() 
{
  pinMode(PIN, OUTPUT);
}

void loop() 
{
  digitalWrite(PIN, HIGH);  
  delay(400);              

  digitalWrite(PIN, LOW);   
  delay(800);              
}
