We will live stream the Google I/O Keynote AND the Developer Keynote which is right after the 90 min lunch break. To bridge the time we will provide the IoT-/Firebase-/Lego-Codelab from last years GDG DevFest, which essentially is playing around with lego and connecting an Arduino with firebase to control some connected sensors, fans, LEDs and so on.
The codelab is optional, you can also just be there and have a drink.
