Introduces the simple concept of reading and writing data to the Propeller's EEPROM with Blockly, using RFID.

You'll also see the FLiP module in there, too! I think everybody will be interested in what that's all about.

    Cool.

    Note: The circuit diagram shows a 2.2K resistor in the serial path. I tend to use 3.3K or higher with 5v inputs. The Activity Board uses 3.9K (limits current through pin protection diodes to 50% of max rating). I would suggest changing that to 4.7K as it's a common value that experimenters tend to have in their kits.

    Gee..We are not supposed to get political on the forums. :)

    Absolutely. We can do that, Jon. I'll add that to a list of small changes we're making to that example. - Ken Gracey
