I wanted to create a kids friendly micro controller. Something he could create the most amazing things with. I made a list of requirements:
one self contained blockit must be easy to use in something my son can build.ports must connect to all kinds of IO (leds, sensors, motors, servo's…)connecting to the IO ports must always be correct (i.e. reversal of the connector must be impossible or no problem)my son must be able to program it himself
