  Arduino Tutorial |   Blink Mr.Easy Arduino, This example shows the simplest thing you can do with an Arduino or Genuino to see physical output: it blinks an LED. Hardware Required Arduino or Genuino Board LED 220 ohm resistor Circuit To build the circuit, connect one end of the resistor to Arduino pin 13. Connect the long leg of the LED (the positive leg, called the anode) to the other end of the resistor. Connect the short leg of the LED (the negative leg, called the cathode) to the Arduino GND, as shown in the diagram and the schematic below. Most Arduino boards already have an LED attached to pin 13 on the board itself. If you run this example with no hardware attached, you should see that LED blink. The value of the resistor in series with the LED may be of a different value than 220 ohm; the LED will lit up also with values up to 1K ohm. Schematic Code After you build the circuit plug your Arduino or Genuino board into your computer, start the Arduino Software (IDE) and...
