From Now On wards I will teach you to make Arduino projects

So our very first project is to blink a LED using Arduino
So let's start it
Here is a fritzing diagram to you to blink an LED

Put the negative pin of LED to the GND pin

Put the positive pin of LED to pin no 13 of the Arduino Board

Here is the code

_________________________________________________________________________________

void setup() {

  // initialize digital pin LED_BUILTIN as an output.

  pinMode(LED_BUILTIN, OUTPUT);

}

// the loop function runs over and over again forever

void loop() {

  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)

  delay(1000);                       // wait for a second

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

  delay(1000);                       // wait for a second

}
