This is to program the Arduino Mega board. Arduino programs are written in the C++ programming language and are called sketches. Sketches are developed in the Arduino integrated development environment (IDE). Sketch files are saved with the file extension .ino.
Connect the Mega board via the USB cable.
Install the USB drivers so that your computer recognizes the Arduino boards.
Select the Mega 2560 from the Tools/Board menu.
You should now be able to upload any of the Arduino programs for ROFI to the Mega board.
