Arduino Uno Rev3 SMD - Hello world, blinking the internal LED

In the embedded/IoT world, blinking some LED (light emitting diode) is equivalent to a Hello World in most computer programming lanugauges. This helps verify that the hardware and connnectivity/interface to the computere is working.

In this project, we are using Arduino Uno Rev 3 SMD.

The location of internal LED is shown below

To blink this LED, open Arduino IDE, then select Files | Examples | 01.Basics | Blink

The Arduino IDE should open with the blinking program loaded

Now, connect Arduino Uno Rev 3 to a USB Type A cable

Select your Arduino device, in my case I only have one and it is called Arduino Uno COM3

Let's now upload this to Arduino. Do Sketch | Upload or Ctrl+U, or click on the button as shown below.

At this point, if the upload went well, the internal LED should be blinking!
