      2. Follow Debian section of NodeSource installations instructions
    • Build essential installed: sudo apt-get install build-essential
    • Add chip user to i2c group: sudo adduser chip i2c

    NOTE: Some GPIO pins require root or sudo.

    Getting Started

    npm install chip-io johnny-five

    NOTE: Must be run on the C.H.I.P. itself.

    var board = new five.Board({
      io: new chipio()
    });
     
    board.on('ready', function() {
      // do Johnny-Five stuff
