EV3 Code Pilot

The first MINDSTORMS programmable bricks, the RCX, had several “incarnation”. Most people remember the yellow brick but there were several others, including the Code Pilot that used light sequences as commands. Those VLL codes could be printed as barcodes:

and the Code Pilot set had a companion sheet with some codes and also key notes that could be used as a barcode piano.

So let’s try a simple set of instructions:

The barcodes are just EAN-13 code generated online from EAN-13 barcode generator. They all start with ‘560’ (the code for Portugal-based companies) and the remaining 12 digits are just 1/2/…/5 left padded with zeros. The last digit is the checksum code and is generated by the tool.

So my first program uses a nested dictionary with the EAN-13 codes paired with an action to be spoken. So the program waits for a barcode to be read, checks for the action to be spoken and execute the action we chose:

The code sheet used and further developments I might make are also at github:
