I got a new Arduino Due but I am somewhat confused about the high number of PINs.
To learn how the pins are wired on the Arduino. So, how could I make a LED blinking, assuming I can run Node.js on my host laptop fine, like in https://github.com/rwaldron/johnny-five/wiki/Getting-Started
- Which Pin group would I need to investigate?
- Which ground pins to wire up?
- Which pins I could tap the signal?
