android app -> raspberry pi -> arduino !!! Answered
I want to make a very simple android app with buttons...
Each button has to be a "shortcut" for a specific command which will be sent from my phone to raspberry pi 3 with ssh..
These commands will simply power some arduino pins to give 5V ( like ser.write('3') which turns on pin 3 ).
But I can't figure out the way to do what i describe with bold... Any help??
