Arduino Software 1.8.1
Software Product Description
You will need an Arduino board and a USB cable similar to those used in connecting USB printers. You may either buy preassembled boards or assemble your board by hand and download the open source IDE free of charge.
Once you have downloaded the Arduino development environment, you must unzip the file without changing the folder structure. You will see a few subfolders and files.
Connect your board to the computer via the USB cable and ensure the green power LED turns on. If it does not, then you need to configure your board to draw power from the computer by changing the position of the jumper connecting two of the three pins you will see between the power jack and USB port. It should connect the pins nearest the USB port.
Please note that although your computer will try to install the board's drivers automatically, it will fail, and you must install them manually. You will get step-by-step instructions, including screenshots.
When you launch the program, you will get an example named 'Blink.' Open it, select your board and serial port under the 'Tools' menu and then upload the program. You will see an orange blinking LED after some seconds if everything is set up correctly.
Arduino's graphical user interface will give you different panes and options for creating and executing programs in addition to making relevant configurations.
