I’ll do More demo, less Slides
Raspberry Pi 2
SoC: Broadcom BCM2836 (CPU, GPU, DSP, SDRAM) 900 MHz quad-core ARM Cortex A7 Memory: 1 GB (shared with GPU) GPU: Broadcom VideoCore IV @ 250 MHz Storage: MicroSD
Raspberry Pi 2 & GPIO
Raspberry Pi OS
New Comer
Windows 10 IoT Core on Raspberry Pi 2
Windows 10 IoT Core Supported boards
Raspberry Pi 2 Minnowboard Max
What to do after install Windows 10 IoT Core?
Code it!
Supported development paths
Arduino Wiring &UWP Lightning Providers
Windows Remote Arduino
Windows Virtual Shields for ArduinoNative
Supported development language/frameworks
Out focus today!
Why JavaScript?

Control the light from Mars….or from anywhere connected to internet
We need Cloud

Light Sensor
Habis gelap, terbitlah terang….or demo to turn on the light when it’s dark,
using light sensor
I made a library to read from MCP3008https://github.com/andriyadi/Win10IoT-
