Flashing LED Light Arduino Code with Basic Explanations

FlashingLightArduino_RawCPP.cpp

//(Remember to use the Arduino IDE) Let's say that you want to make a flashing LED light. 
//In this specific example, the LED is connected to Pin 2.
void setup(){
  //Setting up the output for Pin 2
  pinMode(2,OUTPUT);
}
//In the Arduino IDE, void loop(){} loops the code inside curly brackets.
void loop(){
  //The line of code below turns on the light.
  digitalWrite(2,HIGH);
  //This line keeps it on for 50ms.
  delay(50);
  //This line turns it off.
  digitalWrite(2,LOW);
  //This line keeps it off for 50ms.
  delay(50);
