Step 3 - Test the Development Environment

In this step, you will:

-Use your development environment and upload the blink sketch to your device.
-Observe that LED on the device is blinking.

In order to ensure that your development environment and hardware setup are correct, you are going to use the example blink sketch supplied by Arduino IDE.


Please select Blink example sketch supplied by Arduino IDE.


Please verify that the source code of the sketch loaded onto IDE.


Please select upload by clicking on the arrow icon, or alternatively, you can use ctrl+U for sketches to:

2)Upload to Device
3)And run


Please observe that the compilation of the sketch has started.


The Done Compiling message indicates that compilation of the sketch finished without any problems.


When you saw the message CPU reset, It means that your sketch had been uploaded and the device had started to run. Because when a sketch loads into memory, it automatically starts to run.


Please observe that the LED started to blink. It shows that your IDE and device are working together without any issues.

As a result of this step, you ensure that your development environment is setup properly and working with your device, which is connected via the USB port of your computer.
