pyDarts official wiki

Now that your board is done, transplanted and nice as shown in the previous step, the hardest is done. You need now to upload a small piece of code in your Arduino controller.

To do so :

1. Windows users : install Arduino drivers furnished in the pyDarts package : folder “arduino/arduino_drivers”
2. Download and unpack the arduino administration software from the Arduino official website
3. Unpack the latest pyDarts package. (Let's interest to “arduino” folder for the moment)
4. Plug your arduino controller into a free USB port
5. Launch the arduino software. Click “File” > “Open”, one of the sample files furnished with pyDarts (in the folders “arduino_uno_config_XxX_sample”). The files are .ino files.
   
   This opened file looks like this piece of code :
   
   Adapt it to your configuration ! The rows and cols must corresponds to the solders you did previously. This is one of the most important step and you MUST understand it before going further.
6. Click on the “Upload” button (the arrow pointing right) to send this configuration to your controller.
7. Close the Arduino software, you're done for this part !

Your board is now ready to play. Double-click on the pyDarts executable file, and have fun !
