Clone or download the repository from the official GitHub page: https://github.com/dilshan/tiny-basic.

1. Open the downloaded project folder inside Visual Studio Code (ensuring the PlatformIO extension is installed).
2. PlatformIO will automatically evaluate the platformio.ini configuration file and retrieve the required toolchains and framework dependencies.
3. Connect your Arduino board to the computer via a USB cable.
4. Select your specific target environment (either due or uno_r4) from the PlatformIO project tasks panel.
5. Execute the Build task, followed by the Upload task to flash the binary onto the MCU.
6. Launch the PlatformIO Serial Monitor or any preferred terminal application (such as PuTTY or minicom).
7. Configure the serial connection parameters to a baud rate of 9600.

Upon a successful connection, the Tiny Basic prompt will appear on your screen. You may then execute scripts as follows:

10 PRINT "HELLO FROM Tiny Basic!"
20 END
