Hi all i would like to ask if Lilypad main board can be used to replace the Arduino ProtoShield kit ? is it functioning the same way as Lilypad board? :-?
No, the LilyPad Main Board has a micro-controller, where as the Protoshield is just a open-source prototyping shield for Arduino NG/Diecimila with no built in micro-controller.
LilyPad Main Board = Arduino http://arduino.cc/en/Main/ArduinoBoardLilyPad
Protoshield = Shield http://www.arduino.cc/en/Main/ArduinoShields
