ADC Demo - Coding for Digital pin 12

I downloaded “” and extracted it and put it into Eclipse. I compiled it and loaded it on to my Tablet. Among other things, it is supposed to toggle Digital Pin 12 on the Seeeduino ADK Main Board.

This may seem trivial, but please tell me where in the code that digital pin 12 is designated. I would like to change it to a different pin.

Please refer the … ->Android application essential sends commands to ADK board to control the LED. It is the Seeeduino ADK sketch which responds to the commands using MCU code.

Hope this clears your doubt. If you are totally new to Arduino / Seeeduino please refer to

Thanks to “viswesr” for the reply. Not only does it address my question, but is useful for those new to Arduino. :smiley:
