STEP3 Connect Crowduino Uno to PC via a Mini USB cable.


STEP 1 Download filesArduino_Demo_code_ArduinoUNO&

STEP 2 Configure controller board&communication port
On top of the Arduino IDE, click “Tools>Board>” and select “Arduino Uno”from the available options
Select the COM port that indicates Arduino Uno. Please note that the actual numbers after the “COM” word will vary from computer to computer, so they could be different from the ones shown in the figure.

STEP 3 Install Library: Unzip the Arduino Demo code_ArduinoUNO& file. Copy the dependent libraries in the Install libraries directory in the package (shown below) to the Libraries directory under the Arduino installation directory

STEP 4 Open the sample program in the Example directory of the package to test

STEP 5 Click the Upload.png to upload the code to the Crowduino board

STEP6 After the program is downloaded, run it directly and observe the running status. If it can be displayed normally, the program runs successfully
