First microcontroller program - Blinker

Good morning.
Today we present the first program for the Arduino microcontroller.
For this practice we need:

1. LED diode
2. Cables
3. A resistance of 220 Ohms. (Not to burn the LED)
4. An Arduino microcontroller.

Steps:

1. We connect the positive of the LED to the 0 port of the Arduino.
2. Connect the negative of the LED to the resistor.
3. Finally the resistance to the GND port of the Arduino.
4. We program by blocks so that the positive in the zero port opens 1 second, then closes 1 second, the program will be repeated infinitely, so the LED will be flashing.
