Getting Started with keyestudio
Displaying Hello World
Generally, teacher will teach us to write a simple Hello World example when starting to learn a programming language. Although it is only a basic introductory，it is a very important step for you to learn it. Please don't worry that you are not familiar with Arduino.
Here you can learn the hello world program about Arduino: lighting up an LED. Now we take keyestudio UNO R3 Board as an example to help you how to light up an LED controlled by digital 13 pin.
Before doing that, please make sure that you have downloaded the Arduino IDE and installed the keyestudio UNO R3 Driver successfully. Please refer to the following steps:
1.Connect keyestudio UNO R3 Board to the PC
Connect the keyestudio UNO R3 Board to your computer using the USB cable. The green power LED (labeled PWR) should be on.
2.Set Editor Language of Arduino
Here, we choose English language.
4.Select Your Board
5.Select Your Serial Port
6.Upload the Program
Now, simply click "Upload" in the Arduino IDE. Wait for a few seconds - you should see the RX and TX LEDs on the board flashing.
If the upload is successful, the message "Done uploading." will appear in the status bar.
Waiting for a few seconds after the upload finished, you should see the pin 13 (L) LED on the board blinking.
If it does, congratulations! You've gotten Arduino up-and-running.
